Having been using Windows Mobile based phones since the iMate Jam back in 2004, I would say that I have a little knowledge when it comes to touch screen phones using windows mobiles.
I am a little surprised by people who have been leaving this phone low feedback. Granted this phone has a few issues, with regards to the video performance but there is no way that this phone is a 1/5.
Prior to this I had the HTC Wizard or T-Mobile Mda 1 which was the first qwerty slide out Keyboard device HTC made. That one was an absolute nightmare out of the box and used to die on me all the time, however over time with updates it got really fast. In fact it was so good that I was a little disappointed when I upgraded to this machine.
Having said that this phone has it's advantages over the previous phone in that the screen is better, the keyboard is much better and it has built in GPS and 3g which I use all the time. TOMTOM works on this phone as if you have a real TOMTOM and picks up the satellites very quickly.
After having installed the Opera Browser I surf the web with the 3g connection all the time and I often tether it to my pc using the built in internet sharing application to surf the web on my Laptop anytime I am out and about.
People who're buying this to use it for Excel and Office applications are kidding themselves. How are you going to work on an Excel spreadsheet on a 2.8inch screen. Come one!
The phone could be faster, but it's not as slow as the people here are complaining about, my Girlfriend has a Nokia series 60 phone which she's always complaining freezes on her and I have people at work who have iPhones and their phones are always freezing on them as well. You take the rough with the smooth. People who own Ferrari's don't complain they have to have them serviced every 4000 miles, just like people who have Off roaders can't complain that they can't take corners like a hot hatch. You have to take the rough with the smooth.
If you want something which has great call quality, Surf's the web, sends emails, syncs easily with outlook; You can do some minor office work on it. Has SatNav facility, send's MMS's, Sms, has built in Wireless Lan, has built in Msn Messenger, you can play basic games on, Listen to music, watch some movies (screen's a bit small) and basically organise your life on the move, this thing kills the iPhone hands down. Granted the other one looks cooler and has a better OS. This thing has much better GPS functionality.
Bottom line is, you can get individual device's which will do all the things this does much better. But this Phone is great at doing lots of things. Granted it's doesn't do every one of them perfectly, but as a convergence device this thing Rocks. Would have been a lot better if they had sorted out the Hardware Video driver issue's but I still like my phone which I've had for 5 months.
