Yes by about 10%. Thats on performance power plan. 32 bit

Yes by about 10%.

Your mileage may vary. Note this TechRadar article, Windows 7 Shames Vista on Battery Life where it correctly states,

If a notebook runs Windows Vista, it will run Windows 7 and it will get better battery life... . But PC manufacturers and device suppliers are also going to have to do their part to make a big difference to power consumption on new notebooks.

Bottom line, MUCH depends on the hardware's power saving features.

Cool, thanks!! I've ordered a hdx16, with vista for a windows 7 upgrade, hope it will save me quite a bit of battery..

I don't see any significant difference on battery life. I have a netbook with a 128gb SSD and the battery meter calculation is the same.
