I've several boards (from Ti and ST) with micro-USB here, and they have 
four holes to keep the connector on the board (all four holes are ground, 
the signal connectors are SMD). So it's actually possible to have those 
connectors robust.

The USB board of my Galaxy Note 2 (soon 4 years old) also is made that 
way:

Here you can see one of the more robust ones in all details (from LG this 
time):

connector,a,de,810149.html

So it is possible to have a robust micro USB, but maybe some 
manufacturers prefer planned obsolescence.
