I've phased laptops out of my life. I currently use a tablet and a desktop I built. I've also taken it a step further and I use mostly cloud services (dropbox, google docs, google voice voip, etc. etc.). Every service I've ever used in the past across multiple platforms works seamlessly (sync etc.) and perfectly across these two devices. I really only use the desktop when I need to "finalize" a project or do some heavy coding (multi-monitor setup is infinitely more productive than a small tablet display for coding).
Pretty sure Google owns me right now but I'm loving the luxury and productivity of the whole setup. Sometimes I wonder if it's their plan to monopolize... everything related to technology.
On a side-note, I considered one of those Google chrome books at one point but those are just fucking stupid. Gimped hardware at the price of a half-decent netbook or ultraportable, with literally no advantages? No thanks. I can accomplish everything those have to offer with android apps anyway.
If you haven't made the switch to a tablet, start looking into it. With a simple bluetooth keyboard (or even a full-sized USB keyboard if you're not a masochist) and a decent folding tripod it's easily the most versatile and convenient piece of tech I own. Expect some awesome advances in tablet tech coming in 2012 as well.
