Im just going to say it again, mine is faster and more snappy now, not like 2x but i can defiantly see it, something as simple as opening calculator took longer at 128 then now, every thing else opens just as fast, when i press "Contacts" it opens up as fast as i can press it and have all contacts displayed in the blink of an eye, the same with sms/messaging and here i would like to point out the there are LOTS of texts in there.

In the camera sense, more frames in viewfinder in 576p & 720p, this is not important but shows an extra performance.

In recording 576p is still full on, no dropped frames, 720p still suffers from dropped frames but is FAR LESS then before, i have not OC DSP on mine, if i did i could probably record 720p, but looking at the recordings on big screen there seems to be very little gain anyway.
There is how ever a much bigger gain from normal recording (high 16:9) to the DVD16:9 (576p)

I really find it strange that you can't see the performance boost, can't just be me and Gusse that can see it, and he actually have 2x N900 to test it with.
