While some of my posts have discussed the one-handed operation of the Treo 650 to the HTC Wizard, I just want to say that it isn’t an apple to apple comparison since the Wizard is really not designed to be used as a single-handed device and the only true comparsion would be with the Windows Mobile Treo. I am trying to personally decide if one-handed operation is more useful to me than two-handed operation.
Now as far as two handed operation goes, I still think the Treo may hold an advantage due to the superior camera, faster processor and switching speeds, superior RF signal (to be verified with production Wizard), and amazing display. I can still type faster on the Treo 650 because my fingers have less distance to move and I have no problems with the tight keyboard. I do like the Wizard keyboard for the most part, but I would like to get even more functionality out of it (i.e. cut, copy, paste). On the Treo 650 you can press the dedicated Menu hardware key and then a letter to cut, copy, paste, undo, select all and the shift key and space bar to tab. There are also several 3rd party free utilities like TreoSelecText, CutPaste5, and ShortCut5 that are quite helpful.
There are some useful tips and hacks already being posted on Howard Forums. I used the ClearType for landscape hack and also like this tip: If you hold the Wizard in your LEFT hand you can slide it open just a bit and have access with your thumb to both the “Start” key and the “OK” key. This tip here looks to solve a BIG issue with me not being able to get to the Start menu or OK/X button.
