Very interesting comments. I knew there had to be a lot of people like myself debating back and forth on whether to upgrade.
At this point I have 8 more months on my current sero contract, and I have my phone on the full insurance program (TEP). I already had to have my mogul replaced in June last year because the data cord port stopped working (couldn't charge or sync).
I'm not hoping for this, but there is the possibility my phone could have another defect and when I go to get a replacement they give me a refurbed TP. That would be called a "forced upgrade"
If my mogul had a faster processor and 64-128 more megs of ram, I wouldn't give upgrading to the TP a thought.
