see the link.. the back of m610.. the camera to exposed to scratches ler..

Even though the camera and wifi look tempting, but I think adding these 2 not only adds weight n thickness, it also make the price blast past 2k I think.

I like M600i for it being a PDA and lightweight (lighter than Xda2 Mini).

You have forgotten one thing, the US dollar is no longer pegged in Malaysia now so it should be USD900 X 3.4 (current exchange rate) = RM3060, +/- RM100 since the recommended retail price might be USD900 but who knows, maybe they do give discounts for it. I guess based on the price estimation, we can assume that it's roughly the same price when P990i was first launched last time and should be cheaper for AP sets. Knowing SE is famous for slashing the price of their P series after 6 months to 1 year, I guess I'll prefer to wait until it goes down until a very reasonable price range.
After owning a P990i myself, I share the same worries as you. Guess, it's best to give the P1i some stress test to make sure that it's really that stable as the current Symbian OS is quite resource hungry.
