my T41 is 14.1" - it's a good size
but at 2.2 kg it's a bit heavy to carry around
so the 12.1" compromises on the size but it's lighter, may be good
for me
i wonder what's the size of the small vaio?
but heard that the specs are not very good - not very powerful
although it is small and handy
i use the nipple smetimes but i seldom use the trackpad
