I'd like to upgrade to a new lightweight laptop like the 1.4GHz Dell X300 (3 lb., 12" screen), but am somewhat concerned about the small screen and keyboard size. I currently run a 4-year-old, 800MHz Dell Inspiron and have little problem running R6 server and either an R5 or R6 design client simultaneously. I am therefore not too concerned about performance, but am open to any thoughts on that issue.
Does anybody do heavy development on a small laptop like this? If so, I would love to hear any comments, good or bad, on how well it works for you, or recommendations for other laptops in this category.
