I've now got this phone on O2 and I have to say after jumping into the windows settings and tweeking a few things it is a delight to behold and use.
The multiple input options offered by Windows Mobile are good, and the screen is big enough to use the transcriber input well. Failing that you can always use the old 3 by 4 on-screen input method.
Performance is good, can be improved slightly by disabling Touch-Flo but the TF3D interface is pretty snazzy.
Camera time of 7 seconds is only first load, you can just keep it running as a background task, it is true it does take a few seconds to take a picture when you have automatic focus on but it does give you good quality snapshots.
Lack of flash is a bit of a downside though.
Has good software features and configuration options such as the touch focus and optional back light and shutter sounds. Not too good on the effects aspect with only Grayscale, Sepia and Negative available.
Has lots of decent applications installed by default including the mentioned Google Apps, and the GPS is quick to pick up.
Choice of Opera or IE is good, although installing Flash add-ins for Opera is going to cause you a few headaches.
Having Mobile Office is also a handy thing to have about when you receive documents as email attachments on the go and would previously have found yourself without a way to view them.
The phone dialling interface does its job although you can occasionally go clicking on peoples names or such expecting a menu and instead finding yourself calling them immediately leading you to tap like a madman at the end call button - a confirmation here would have been useful.
If you're wanting to get one of these phones you'll also want to invest in a MicroSD card, I just paid £17 for an 8GB class 4 card off eBuyer and the phone is much better for it.
The TF3D media player is not much to look at but that is no problem as you can turn it off and use the Windows Media Player with ActiveSync to play your music with a lot more freedom.
The included YouTube app is strange, as it finds videos in a different way to what you would get if you did a search on the website, often missing the ones you're after.
