My first Palm was 2 Meg and I got along just fine with it. Now I can't

No need for cell signals if you don't want a phone. When you put a
smartphone in Airplane Mode they are really just a PDA with laptop
(and WiFi) capabilities. Check EBay for some good used prices. A new
toy for you to check out...

Use both. You do now (your netbook and your Palm).

The Palm IIIc was what I consider my first PDA. Although it really 
wasn't. I bought two really cheap PDAs before that. They were under 40 
bucks brand new. They had some PIM stuff, but that is it.

But the Palm IIIc cost over 300 bucks. And if I remember right, it was 
the first color PDA. I *love* tech things that was the first. Later I 
bought a GPS for the Palm (this was before cheap GPS gadgets). Although 
it was really made for the Palm IIIxe and not the IIIc. At the time, I 
thought the xe was the black and white version and the c was the color 
version. Well it is kind of true to a point. And anything that ran on 
the xe would also run on the c.

As the c was a tad longer from top to bottom. And this GPS clipped on 
from top to bottom. So I could make it work if I held them together just 
right. But not very practical. So I bought a xe just for the GPS.

I learned there was more differences too. It only had 2MB of memory and 
ran off of two AAA batteries. As I liked the color display so much 
better and the chargeable lithium battery on the c. And I gave up on the 
GPS and the xe soon afterwords. But I kept using the c to this very day. ;-)

Oh okay. I'll add that to my todo list on my c. No seriously, it sounds 
interesting.

Oh great! ;-)

As a side note: When I was younger, I was *big* on the latest and the 
greatest. Although as I age, what seems more important is collecting 
devices that were noteworthy and important for their time. I dunno, 
maybe it is just watching the clock tick along or something. :-(

That IIIc color screen is a bit grainy at 160x160 resolution (My Droid
is 480x800). Also it was impossible to see in direct sunlight. Later
color models had the transreflective 320x320 screens which was a big
improvement.

That was basically true.

>I learned there was more differences too. It only had 2MB of memory

The IIIxe had 8 Meg of memory just like the IIIc. Maybe you're
thinking of the III which had 2 Meg.

Another advantage of the B&W Palms was that you could easily read them
in direct sunlight.

>and ran off of two AAA batteries.

I had an aftermarket rechargeable battery pack that fit into the
battery compartment and sported a charging jack for the wall wart. It
was kind of a waste though since I got around 25 to 35 hours on a set
of plain old AAA alkalines. 

> And I gave up on the GPS 

Another clip on device I had was the dialup modem. Course using the
thing in those things was like watching grass grow. I'm not sure which
was slower, AOL or the Palm... ;)

The battery in my HP/Compaq dv9500 was pretty much dead after 3 years. I did 
not want to pay $100 plus for a new battery so I just kept it plugged in. 
After a year I decided I needed the battery. I couldn't believe those $100 
batterys were now selling for $30 on Amazon.com. I bought one and so far 
have no complaints. A few days later I saw a documentary on the problems 
caused by product knockoffs, mostly from China. Laptop batterys were one of 
the products they talked about.
If my laptop battery is dead within a year I'll know it was probably one of 
those knockoffs.

I just got a new used laptop and the battery doesn't last too long. Some 
places I read says to let it uncharge all the way a few times to restore 
it to full capacity. Would that work? I like to leave the laptop plugged 
in all the time but now what I read here is that's a bad think to do.

What technology is the battery? Lithium based ones don't like that, you 
just eat an extra cycle from the lifetime.

Used? Probably 80% chance it's a bad battery. But what do you use it
for? Video really sucks the juice. And anything running in the
background? These types of things can really shorten the battery life.

If it's an Li-ion battery some laptops manuals say to discharge the
battery down to automatic turnoff once every few months to recalibrate
the battery's microprocessor. Others are 'precalibrated' and have no
such instructions. What does your manual say (if you have or can find
one)? Probably wouldn't hurt to try it once just to see if it helps.

>I like to leave the laptop plugged

Mainly because the laptop heat reportedly reduces battery longevity.
Personally I find it a hassle to always go hunting up the battery
which may or may not be fully charged when I want to go mobile so I
just leave mine laptops plugged in all the time. I've yet to have to
buy a replacement. The one I'm using tonight (Acer 4315) is 4 years
old and has been plugged in its whole life (whenever it's not mobile).
I'm sure the battery has lost some capacity over the years but it is
still quite serviceable.

The BatteryCare app may help you determine the status of your laptop
batteries as well.  It monitors discharge cycles, temperatures readings,
calculates the statistical remaining time the battery has left; and
shows wear level, capacities, consumption, manufacturer, etc.

I've not known laptop lithium batteries to last longer than that. Three years
is more par for the course, and their usable capacity is already on the slide
by the end of the second. The laptop I'm typing on is entering its sixth year,
and has its second battery in place, which is already down to about 20% of
original capacity. As the system is set to shut down into hibernation at 15%
(a seemingly vain attempt to prevent over-discharge and the lifespan reduction
that causes), that essentially means the machine is completely tied to the
mains and the battery is only really useful to keep it alive for a couple of
minutes when moving it between rooms (or sockets in the same room) without
shutting down, or as a safety "parachute" if there's a sudden power cut.

That doesn't mean the power supply is behaving itself however - I've had to
get an HP-Compaq laptop PSU replaced before as it failed in such a way that it
had just enough power to run the laptop in light usage conditions, or charge
the battery in a slightly sluggish fashion when the machine was turned off,
but not both at the same time (and high power use would gradually drain a full
battery). Whilst the battery is almost certainly dead, its death might have
been hastened by a dicky supply. Sadly the only way you can really test it is
by installing a working battery and observing the power-on charging behaviour,
maybe with a third party battery / power use monitor utility (or an OEM one if
they bothered to supply such). With the battery fully drained, it should be
able to charge at a rate representing 0 to 100% in under two hours (or just
one hour for some models), which then tapers off above 80~85%, with the
machine turned on but idling or only working lightly. With the processor,
graphics and disk working hard, that rate shouldn't drop to less than half and
there should still be a taper-down noticeable above maybe 90%. Alternatively
you can plug it into a power meter and see how much the PSU draws. At full
tilt it should be somewhere around the rating printed on the body; if it's
significantly less (below 75% or so, and particularly under 50%) even with the
cooling fan howling and your lap being thoroughly cooked then it's probably
defective.

An eight year old laptop, though, that's very much prime for replacement. I
keep my computers running as long as reasonably possible, and then a little
more, and I've not yet managed to keep a machine operating in a satisfactory
manner with contemporary software much beyond its 7th year. At least not for
those of middling to slightly above average performance, which tend to be the
best value (not "cheapest"). If it was originally a top-of-the-range model I
guess you may get an extra couple of years (I've seen Core 2 Duo/Quad desktops
stretch well into their 8th year whilst still being just about usable), but
even then I'd suggest you'd be better off resigning to the idea that it's had
its day, and the failed battery and potentially iffy power supply are good
reasons to replace the entire machine. You've definitely had your money's
worth out of it, and even the cheapest, nastiest machine you can buy now will
significantly outstrip a high end machine of 8 years ago in terms of
performance. I'd be looking to replace this one already (the generational
shift to 64-bit operating systems is increasingly leaving me disappointed when
looking at the minimum specs of otherwise attractive software, as it only has
32-bit Windows and there's no point spending money on an OS upgrade for a
machine that may only have another 12~18 months of service left in it), if
only I wasn't out of work and increasingly short of cash right now.
