I was quite sure that Raid was not an option for a laptop but Kenneth comment with this idea about my laptop (future) backup:
I use a notebook with a wireless adapter as a "terminal" into my development server using Remote Desktop Protocol.

USB RAID is not an option? Think twice :-). But seriously, I cannot think of my development life as meaningful until I bought and installed Norton Ghost. 14GB of stuff from my laptop (and where does it come from?!) backed up to my desktop over 100MBit wire in under 40 minutes, restore took about 25 (thanks to compression, I guess). Recommended.
Next item to buy: Lacie PocketDrive. The backup should be even faster.
Word of warning: DO NOT upgrade Ghost with LiveUpdate without following it up with fresh backup. Updated application cannot restore images created with previous versions. That's right, your previous backups are useless until you reinstall Ghost. That's just plain stupid, if not criminal, IMHO.
With the arrival of NewsGator integrated publishing and with a few people keep telling me that I should really start blogging, I guess, I have no option but to do so :-). Thanks to Scott, I now up and running.
Not to forget that I survived a very painful experience to tell about and not to mention finally finding a correct spelling for doh!.
