I always try have two devices, a desktop or now days, larger laptop; and a smaller more portable one. I find that when I work on my primary machine (and either one could be primary for a lot of tasks), the other is plays the role of email, music, quick research checks, etc... This secondary role has been my aging SP2 and to see the demo of the SL has me smitten. And not even needing the highest spec'd out one, the i5 256 would be totally adequate for what I want in an SP2 replacement.
