Treo 650, LifeDrive, or Tungsten T5?


I'm looking for a "do-it-all" PDA (or at least as close as I can get). The problem I have is that they all seem to have "issues".

Tungsten T3 - Seems like the best all-around (in terms of power and syncing issues), but I keep reading that the battery-life is horribly short.

Tungsten T5 - There seems to be a lot of syncing issues and/or bugs.

LifeDrive - Not FULLY supported by Mac and also has its set of bugs.

Treo 650 - I was hoping to keep my phone and PDA separate, but what all-in-all, it seems to be a good machine. I don't like the screen size and the CPU is slower than the other ones I've mentioned.

Here's what I want in a PDA.

1.)Complete syncing with the Mac. I use Address Book, iCal, and MAIL. I switched from MS Entourage to all Mac apps.

2.) Play full length DVD movies

3.) Good battery life. The T3 goes down after one full lenth movie from what I read.

Am I asking for too much?!
