I've been working with three different laptops for the last few months, and my conclusion is that it really depends on what you're doing. If you have a lot of license keys to juggle or finicky software that wants a very specific install environment, it's just plain easier to use one computer. And if you have tons of media sitting on Dropbox, it can take ages to do the initial sync after a reinstall, even if you're only using the 2GB free account. And my EEE 900's flash drive doesn't play well with Dropbox and turns the whole desktop into a nightmarish stop-start experience...so it's been relegated to being almost purely a web machine. But apart from those things, my cross-computer experience has been pretty good.
