Got my hands on the nokia 6600, a really good looking phone indeed. It supports the new MIDP 2.0 and MMAPI in fact it's one of the handfull of phones around that have both these features.
The good looks are mostly due to the fact that it has a 65k color screen that's leagues ahead of my siemens S55, then again the S55 is only half the size of the 6600 and it's a handy phone. The 6600 on the other hand doesn't really feel comfortable in your hands.
Still trying to figure out how to use all the features of this phone, look forward to a follow up post.
