Netbooks comments?

[mark]

Looking for some feedback on 10" netbooks. Any big cautions or negatives?

Because of the hassles of carrying full size laptops on northern flights (need to be checked baggage, so then a hardcase, then weight and excess charges and limits etc), thinking about grabbing a few netbooks.

Use mainly would be for filling in checklists (Excel and Word 2003 based) and checking mail (through a internet server so don't need Outlook).
