This year I switched from a TX to the Centro. I got tired of looking up a phone number then punching it on my phone then not having all my numbers on my TX on my cell phone when out on errends. Pain carrying 2 devices. The screen size is small but HiRes and for lengthy input I use a computer. I had the Treo wx before the TX but hated it. WIndows mobile was buggy and lost my sync data constantly w/missing sync.
Now all is good and smooth with the centro. I sync via Hot Sync got rid of Missing sync and work flawlessly (except for a minor mishap last month). I also then sync up w/google cal so my wife and I can share a calendar.
I do have Action Names which makes dates/entries easier.
Once the 3G iphone comes out I may swich over to that?? lol. The last thing I want to do is surf a "real" internet not blazer.
