Paul, I went to http://pdadb.net/ind...p?m=pdacomparer
One had to be closed, doesn't really matter which... longer term I think the review thread is where people will go!
for a short comparison between tytn and kaiser. Seems that htc is offering limited improvements(the nice sliding panel, nice double hsdpa, hsupa and...gps...well I use gps external module since I bought my tytn) and is taking away some good communication channels(irda out, one umts band out) plus extra weight. Considering this is not an official advertising site for htc I have to ask for a good argument to drop my wm6 tytn for kaiser(the cpu clock speed is also lower but technical specs seems higher as far as I red).
