T61 or X61 tablet ?

I am trying so hard to detemine which (if any) to buy.

I have a dell precision M90 (17 incher, 9lbs), which is great. However, I travel occasionally, and the hotels I've been to dont have a safe. As a result I end up carrying the laptop everywhere, and I hate that.

So I was thinking of getting a smaller laptop. I really need at least SXGA+ screen resolution.
Here are the candidates:
T61 : WSXGA+, 2 Ghz,Nvidia140M,
5 year depot warranty: $1285

T61p: WUXGA, 2Ghz, NVIDIA Quadro FX,
5 year depot warranty: $1485

X61 tablet, SXGA+, 1.6Ghz LV, integrated graphics,
4 year depot+accident protection: $1560

This is after tailormade and fastcash and coupons.
Trying to decide which way to go. The main selling point of the tablet is its lesser weight, not too keen on the tablet feature. But the T61s are so much more powerful....
Will the extra 1.5lbs really make that much of a difference ?

Any opinions ?

 

Is there a reason why you can't get the non tablet? or do those only come in XGA?

If you don't need the tablet functionality then don't get it. (waste of $ imo). The 1.5 lbs isn't a huge difference, but the footprint of the T61 will be fairly larger.

 

Yeah unfortunately the non tablet X ones only have XGA.
