I've used three different Palmtops over the years starting with Palm IIIx.
There are two types of PDAs ones with Microsoft operating system and ones with Palm operating system. I think Microsoft system can do more, but can also crash, which Palm tends to do less.
Personally (this is just me talking) i find them too small, i tried it once, but gave it up, and went back to a laptop. I like the power and vercitility of a simple laptop over a PDA, though it is larger to carry, i've made my choice, lol
Anyone know anything about the new windows treo? I heard it is pretty nice, but some people complain because it is not like a palm or has different software or something.
