I was using a Windows Mobile O2 XDAIIi for more than 4 years & was quite happy about it. Recently the battery started to last less than a day; so I had to look for another phone & I selected HTC Touch 2. Form Factor wise, it is quite good; particularly in comparison with O2.
However I faced the following set-backs over my old phone. No graffiti input (handwriting recognition - which was my choice of data input all these years - Palm Pilot - Sony Clie - O2 XDA
Very limited cut and paste interface. The windows > Start >> menu also presented in a weird & user-unfriendly manner
In my phone I am getting the call log registered for only about 2 weeks. I found no way to alter this.
If you are new to Windows mobile, this phone might pass for you If you are an upgrader from previous Win Versions; then I suggest that you give this phone a miss.
