I've searched and read about the various options, but I'm still a little confused.

What I want is to leave my heavy and cumbersome laptop at home when I'm traveling or doing work on-the-go.

I absolutely need:
- internet access (WiFi required, connectable would be nice as well) and browser
- skype
- e-mail
- word processing of any kind- even a notepad style package would be ok
- small portable keyboard I can plug in (not Bluetooth), so I need a port
- small and lightweight!!!

I would like (but absolutely NOT necessary):
- movie viewing capabilities
- software installation possible


Ideally, I'd like to spend under $500, and I'm willing to add a portable hard drive.

Any great suggestions?

Thanks,
GG
