This HP Laptop is getting a bit long in the tooth (2007 vintage, I 
think) ... so recently I went on a Shopping Spree and brought myself a 
brand new Desktop for about $700

It hasn't made it out of the box yet .... I'm soooo used to using this 
Laptop on a little T.V. Dinner-type table with the T.V. over the top of 
the screen.

Having to convert to a Desktop Computer just seems to be too much trouble!!
