Palm OS

It depends. Are you looking for a PDA or Phone? I started with the 6700, and it was a freaking fantastic PDA. I had no issues at all. Wifi and EVDO were great. Windows never crashed (compared to what everyone in the US seems to have happen). Plus the expandable Memory.

Now the only problem is that it is a horrendous phone. I mean crap. On your end, the hearing if muffled and quiet (even when maxed). Driving and using it in a public place (like the mall of office) just doesn't work. On the other end everyone told me I was quiet and that I sounded tinny.

I was really disappointed because I loved the 6700 and I really wanted it to work. I didn't want to give it up at all, but I need a good phone, and it didn't have that. So I went to the 650, and it's OK. I'm just not used to the Palm OS. Can't drag or 'right click' with it. Software runs faster on the 650 though. And the phone is MUCH better. BUT it has no wifi, and since we in lovely Canada don't have the 700(p/w) yet, we're kinda restricted.

I've noticed though that Windows based Smart-phones are lacking in the phone area. Good PDA's, bad phones when it comes to Windows Mobile.
