I just got the vx8600 last night, and although it's only been a few hours, I'm loving it so far. It's a little tall when opened fully, but it's no big deal.
I'm trying the VCast free for a month, and I think it's pretty cool, but I don't really care about music or games. I like the unlimited Mobile Web and the news/sports/weather clips. They actually seem to be fairly up to date (although, again, I've only had the phone since last night). I haven't experimented with the Bluetooth yet, nor do I know how to do the whole BitPim thing (I plan to learn!).
Among the complaints I read about while researching was the poor speakerphone, but it seems more than adequate to me. I'll update the post as I learn more.
One thing I noticed is that the wall charger plugs strangely into the phone. You can't really tell if it's fully inserted, which is tricky b/c I don't want to force it in, but I want to make sure it charges.
More later!
