Diamond sluggishness, where are we now?

[pufftissue]

Hi there, I demoed a Diamond in the Sprint store and it was sluggish. I am fed up with my Treo 800w (seems like I've had all the problems that are common to this device), but I had a Mogul that, if it moved any slower, would be going backwards in time.

Is there a stable, fast Windows Mobile device out there that's thin? I like the Diamond b/c it's tiny, but it seemed slower than an HTC Touch that I tried back in the day.

Are these ROMS mature and stable? I don't care too much about gee whiz features, but I do need a ROM that will improve the stock speed and stability.
