But there's no doubt that the idea of pen based computing has come a long way! How long have I been longing for something like the SP3? Since before I got this thing eons ago! That things still tickin' and running Windows 7 Ultimate as best as its measly 512MB of RAM will let it. So let's see... We get with the SP3: over twice the resolution with a real touchscreen, less than half the weight, at least 7x the battery life, actually usable performance, and sooooo much more. So, I may bag on some of the shortcomings of the SP3 from time to time...but that's just because I've got high expectations. It's a great device and I absolutely love using it in my daily workflow.
