get the thinkpad since its 3 years, 3 years vs 1 year warranty a lot of difference.
This is not true.
There are retailers who provided ThinkPad branded system with 1 year on-site, next business day (NBD), 3 years on-site NBD and 3 years on-site 4 hours response 24/7.
The above provides retailers space for promotion (e.g. free upgrade of warranty).
To me, it is not expensive to buy a $2388 X200 with 3 years on-site NBD @ 1.5KG. The reliability and service is more than worth it.
Anyway I paid $2138 for 3 years on-site 24/7 4 hours response plus 3 years ThinkPad Protection for a 2.66Ghz/4GB/320GB/wifi n system. Do not think can be found now.
So wait for the new deals for i3/i5 systems.

Up to your personal preference really, best is to see a demo set.
