I need some help on what to buy and if I should buy. I already own two desktop PCs and a server. Now I am looking for something that I can take with me where ever I go. I just started going to college and I need the following:

Type up papers/reports
Take notes
Record lectures
Browse the Internet
Listen to music
Connect to my 2003 domain at home and remotely

I'm not looking for some gaming machine, I am looking for something light weight, quiet, and easy to use. Should I buy a Tablet PC or Laptop? Is it worth paying abit more for less hardware? And how easy is it to take notes such as in class or would that not work? I want to intergrate my love for computers and communications with my school work. Can I get one around a $1000 range or should I just get a laptop for around $700

Thanks for any replies,
Jeff
