Any usage on top of this will of course drain the battery more. I have only had few hours of time to play around with the device after I had found out a way to get out of the Wi-Fi bug and had finished tests relating to it. As such, I can't really say very much on the real usage time. But based on various usages I would estimate around 2-3 days on very moderate usage, full day on quite high usage and some 6-8 hours on continuous heavy usage.

Yes, that's the right concept but unless 90% of your browsing activities are task oriented then most people will 'spend' the time savings anyway ("Oh, I have 15 minutes to kill while waiting for my appointment"). So in the same amount of time you'll drain the battery more as you plow thru more pages. Yes, you get more data-per-mAH spent, but you'll end up spending more power anyway unless you consciously control the power spending.
Considering that you generally use a lot of time on the web reading text etc, the connection will be idle most of the time. You only gain the saved time on less waiting for page to open. So, if 10 % of your surfing time is waiting for pages to open and it goes down to 1 % (assuming ideal server speeds), you get 9 % more time to use. As such, 10 % of 2G usage doesn't go to 1 % of 3G usage but to 1.09 % of 3G usage. So, the difference is still huge on the time the moderate battery draining is in affect on 2G compared to heavy battery draining on 3G.

And whenever you are doing something real instead of just getting rid of excess time, you will finish the job faster. In case you have something better to do with the time, that is a bonus.
