I went from an R50e to a T60. I love the Thinkpads.
Yes, the Thinkpad T series 14" come in 1024x768 and 1400x1050. The 15" ones come in 1024x768, 1400x1050, and 1600x1200.
These are great machines. Where else do you get sub $1000 machines that are just 1" thin, have awesome battery life (my 6 cell T60 gets 5+ hours with wifi on, web browsing). The trackpoint is essential. You can navigate while keeping your hands on the keyboard, and the middle mouse button lets me open new tabs very easily in Firefox. The keyboard also has great travel and feels great.
For those T4x users who need a windows key, you can map the right alt to the winkey through one of the Thinkpad utilities.
As an example of great value, my friend just got a T61:
14.1" SXGA+ 1400x1050 screen
Core 2 Duo T8100 (Penryn!)
1GB DDR2
160GB 7200RPM (very fast Seagate Momentus drive)
DVD burner.
Price? Just $746.
Where else do you get tremendous battery life, SXGA+, a Penryn CPU, a 1" thin laptop with a magnesium build, and a big 7200RPM drive for under $750?
