My first impressions of the 6600...
1) No FM radio/stereo - my gf's 7210 has this, it's a very neat feature which would have cost bugger all to implement. Very dissapointed it wasn't included.
2) Camera resolution stays the same - hanging out to see a pic taken with the camera, although I can't see it being much better than the 3650 is at the moment :x I thought a flash would have been a great inclusion (even if it had limited range)...
3) Design - not impressed, it looks boring to me. It's another example of building a middle of the road design to try and cater for everybody. Doesn't work on me. Nokia went out on a limb with the 3650 and maybe it didn't work so well for them so they've fallen back on 'bland'. No xpress on covers again mean that if it gets scratched it's $$$ at the nsc to get the cover replaced. The phone still looks like a toy. I would have liked to see it looking more 'corporate' which the 7650 does very well.
This phone has very little at all over the 7650 (apart from mmc), and I would venture to say nothing (hard to guage the os7 advantage) over the SX1.
Siemens still look to be the ones getting the money when I replace my 7650. Let's just hope this isn't the only symbian phone from nokia this year! Although I fear that this one being pushed at the corporate end of the user scale, the n-gage might be their 'youth' phone for this year :x
Finally a question - has anybody seen what spec the processor in the 6600 is? Faster than the 3650? As I understand this to be the limiting factor in the quality of video recording?
