Quote: "Can they access the internet to the point where they can view websites and post to forums such as this one?"
Yes, as long as you have a wireless connection. I have an iPaq with Bluetooth and Wifi so am pretty sorted.
Quote: "can they be used with apps such as msn messenger?"
Yes, but I've never used it on a PDA.
Quote: "What is a reasonabel price to pay for one?"
I'd say at least £200 ($400+) for a decent one, if you hunt around. This is the UK though, so take away at least 30% for most other places
Quote: "Do they come with word prossecors and excel and stuff like that?"
Mine does, but I think they are pocket versions, so some functionality isn't supported I believe.

I am 99% probably lying in bed right now... so don't blame me for crappy typing
