In short, yes - the biggest being that it apparently completely dead as of yesterday.. I took it on holiday and ran the battery right down, and now it's refusing to charge at all - I'm calling O2 to get a replacement tomorrow. However I'm hesitant to say this is a problem with the phone, and instead is more likely to just be a fluke - I haven't seen any other reports of the same problem..
Other than that - the SatNav is extremely capable, but the software itself takes a good two minutes if not more to start up (compared to 15 seconds for TomTom to load on the same phone, although TomTom's a hell of a lot more basic, and in my opinion crap in comparison to CoPilot).. however acquiring a GPS fix is very quick and usually takes less than 15 seconds. I'd say the SatNav is the best feature of the phone, and its made the phone worth the expense.
The camera as you'll probably come to expect is an absolute shambles, and any picture I've tried to take with it is frankly rubbish. I miss my Sony Erricson camera : /
There's a few more niggles - mainly down to having an iPod Touch and realising that the iPhone's interface is much more clean and heaps more intuitive, and with the release of the iPhone 3G I'll be trying as hard as I can to get my hands on one/swap the Orbit II
To summarise - I like the phone, but I don't love it. And all the niggles that at first bugged me to hell I eventually got over and learnt workarounds for. Nice little (mostly third party touches) such as the Spb today screen and TouchFlo menu really add a bit of shine to it, but I just haven't gelled with it as I'd hoped..
I'll gladly answer any questions you might have
