My trusty T41's LCD is snowing intermittently. Illinois roads are bad. 
Worse if you bike to work like me.  I'm surprised it's lasted this long 
with it strapped to my bike. Since I've had good luck with the 
Thinkpads, I'm thinking of replacing it with an X61 -- the 3lb Thinkpad. 
My reservation has to do with its screen resolution.  My T41 is 
1400x1050.  I'd prefer a lower resolution on the LCD.  Things are a tad 
small at this resolution.  But, the increased screen is great when the 
machine is docked to a large monitor.  The X61's 1024x768 will be fine 
on the LCD but am I stuck to this resolution when I dock it?  Does Linux 
support switching resolutions even if the LCD is rated as an XGA monitor 
and the laptop is hooked up to a 1600x1200 external monitor?  Is 
switching resolutions relatively painless?

Thanks!
