"Real World" Netbook Experience - MS-Office, Streets & Trips?

I've read posts and reviews on the Netbooks featuring the Intel Atom. I like the concept; however I'm curious if anyone has any real world experience with how common programs perform on an XP/Atom-based platform.

Intel's web site isn't much help in comparing the Atom's performance to its other mobile chips, so I'm asking for others' experience and feedback.

Right now I have an aging notebook running a Celeron M 1.6, XP Pro with 1GB of DDR2 4200. While not spectaular, it gives sufficient performance running Word 2003, Streets & Trips navigation (GPS attached) and Paint Shop Pro 11.
I would also like to be able to use a USB TV Tuner (very helpful during hurricane season), which the manufacturer states a minimum of a 1.6 Pentium M processor is required for.

Any thoughts would be greatly appreciated. Thanks.
