Well, I already HAVE one. Started with the HP TC1100, but moved to a Gateway E-295C/C-140XL due to the fact that I'd basically be moving from a Pentium M Dothan ULV 1.1 GHz to a Core 2 Duo T9300 2.5 GHz.
Problem is, the E-295C is pretty damned heavy and bulky, with a 17" footprint and a weight exceeding 6.5 lbs., possibly even over 7 lbs. The 14" 1280x768 screen may seem like an improvement over the 10.4" 1024x768 screen of the TC1100, but not when it entails going from BOE Hydis AFFS to cheap TN crap (read: poor viewing angles)...also, for the size, the resolution is lacking, especially height. (I've seen a ton of 12" convertibles with at least 1280x800.)
Also, battery life is lacking at roughly 2:30 on a main 8-cell battery, but it's still significantly better than the TC1100 I had in that regard (wouldn't even reach two hours). Nevertheless, still not enough to the point where I feel like keeping it on AC.
I put up with it anyway because...well, Core 2 Duo T9300. I shouldn't have to worry about software bloat for a while. (But on the other hand, the Mobility Radeon HD 2300...that thing has significantly lowered my opinion of ATI and their drivers alone. It's the biggest bottleneck in this system by far, and I can't do a damn thing about it because there's no MXM slot. It may even be outclassed by the Intel GMA HD on the die of the Nehalem/Westmere chips, and whatever the case, it's clearly weaker than a desktop Radeon 9600 XT.)
