I have both a M1300 maxed out and recently 1Gz TC1100 with 1.5GB RAM and 7200rpm drive. Both run Vista equally well (maxed RAM and 7200 drive critical).
I now prefer the 1100 for general use you describe, the smaller size easier held, the smaller screen/higher res effect a pleasure in-use, but particularly for two other significant reasons: the 1100 has a fan and stays cool indefinitely, the 1300-1400 have none and rapidly heatup pushed and underclock severely to cool down automatically without warning. The second reason is that batteries, docks, etc for 1100's still are easily found on eBay at good prices, while supplies for 1300-1400 are drying up fast.
1.0 or 1.1 matters little, Pentium M only and later series the better. The L2 cache doubled to 2MB on late models. 1.2 supposedly ran hot and fan louder as trade-off. But my 1.0 1MB L2 1100 runs Vista great.
