I haven't had any problems with WiFi. I did notice that the bluetooth turns on when you soft reset, but once it's asleep it shuts off. That's the issue everyone is trying to figure out for bluetooth headsets. It doesn't come on randomly for me. I do miss is being able to connect GPRS by touching the connection icon at the top. There's no option to Connect GPRS anymore. Though with the programs I use that require it, they automatically connect and disconnect when finished.

Certain programs won't work for WM5 unless they are rewritten so you may have to find alternatives. The majority of programs I use are in active development and have WM5 compatible versions. The only program I use that's not is Marsware Weather Panel, but it works so I'm happy. I do miss Phone Alarm, but they are working on a WM5 version.

I did notice that the phone app is faster too. Being able to take down a handwritten note while on the phone is great. The note will even have who you were on the phone with and at what time.

Avantgo sync over USB doesn't work for me either.

I thought bluetooth ActiveSync was easy to set up also.

So far so good.
