So, the advice is: buy a device for 600Euro, crop all the functionality to make it work like 150Euro phone, and still get up to 48h of battery life on the thickest phone in the market ? lol ? N900 is a "charge me twice a day" internet tablet, live with it or don't buy it and don't give others the impression that the battery life can be extended, because it can't, unless you turn N900 into what I described above.
