I won't buy a Treo 600 for a bunch of reasons not listed as options in the poll:
  • No analog for outside major metro areas or for 911 when you really need it.
  • No removable battery.
  • Candybar form factor. Must have flip. Personal preference.
  • Way too big and heavy compared to my SPH-i500.
  • Doesn't come with provided modem software. (Ignoring the fact that using the provided software with my Samsung technically violates TOS... but I only do it in a pinch. Besides, rules and plans can change over time.)

I'll admit the thumboard and newer PalmOS and faster CPU and more memory are tempting. But not worth the trade-offs (for me). Just my situation and parameters; others may vary!
