I forgot to mention this last night but yesterday I got a rough idea of how poor 2.0 is in its current state on my 1gb touch.
Every morning I would leave my house with my jailbroken touch and full battery and at work leave the touch in sleep mode. Intelliscreen is the only background app that regularly updates itself with notifications of my newest emails/calendar events. At the end of the day the battery meter would be just over the halfway point, or at 76% according to a third party battery app.
Yesterday was my first day with 2.0 at work with no intelliscreen app (doesn't abide by daft apple rules) so I had Push up and running instead. As I left the office I noticed the battery meter at less than half full (around an estimated 35%). Shocking.
Yes the 'test' above isn't a thorough one but my daily usage remained the same. Even worse was to come during music playback. If I hit the sleep button the music stutters horribly for a few seconds - sounds like a huge cpu hit for those few seconds to me. Urgh, giv 1.14 back plz
