I am looking to buy another computer to use for school. Here is what I am thinking and I would greatly appreciate any insights into this. I will be using the computer for just standard MS-Office/OpenOffice tasks; nothing elaborate.

My thoughts are to try and use a Toshiba/Asus style netbook. I would attach, via USB, a keyboard, mouse, and a 15" LCD Monitor to it. The thought being I can reduce the carpal tunnel problems with the keyboard/mouse and save the neck pinched nerve problems on the neck I have. I will still have a tiny form factor for portability if and when necessary. Will the ATOM processor that these type computers come with be up to the task?

The other option is to spend $250-300 (minimum) more for a 15"-17" laptop and essentially do the same thing minus the external monitor.

I thank you all in advance for your help, insights, and opinions.
