That's why I said that if you want one
now, the DR1000 is rally the only one that meets your requirements. You do also have the option of getting a tablet PC, but from what I have read, they're underwhelming.
Of course there's
always something better just around the corner.
You have to look at what you want, what you have to spend (not what you want to spend, but what is your actual budget), and then do a cost/benefit analysis. Don't forget to include things like the ability to take all your textbooks to the cafe to study with.
You may find that the DR1000 is what you want. You may also find that it's too expensive and a netbook will do the job just fine, and couple that with a less expensive e-reader for occasional jaunts.
We all have our opinions and are just dying to give them to everyone, but you need to figure out what's best for you, based on what we've all done.
Happy hunting
