I dunno, out of the PC laptops I support most are used as desktop replacements (so are better if larger - ie. A600 sized keyboard, 15" screen), and 95% are only used when plugged into the mains (having tried to use regular TFT in daylight, the only place you're likely to have a real use of batteries is on a train - which I tried once, and got motion sickness - or in a Cafe or similar). This ties in with my personal tastes, but only after trying it all for myself.
So in conclusion, bigger, and mains power for me ;-)
