The first computer I ever used regularly was technically a laptop. However, it was extremely old and chunky (over 1" thick), and the screen had literally broken off. It had an external monitor attached to it, so it pretty much functioned as a desktop. Other than that, all my primary PCs have been desktops. I must say I just love the power, better screen size, and full keyboard that I find in desktops. My current desktop I custom built in September with a quad-core 3.2Ghz Phenom, 8GB memory, a good discrete graphics card, and USB and SATA 3, with a 7200RPM drive. By recycling some parts, it cost me only $300! To get a laptop this powerful would cost well into the thousands of dollars, money I just don't have. So, I much prefer desktops, which isn't surprising seeing as how I don't travel much. I do have a secondhand laptop, and I think it's getting ready to bite the dust. But, it does still work, and it's usable for the times when I do travel (like now, actually).
I do agree, though, that it is getting harder and harder to "get away from it all". I live in New England, and as some may know, we were hit by an early snow storm on Sunday. This wouldn't have been a problem, but it being early, all the leaves were still on the trees. When the heavy snow fell on the leaf-laden trees, they all went to pieces, cutting power in 6 states, including ours. One would think this would cause a forced exit from technology, but the next morning, out came the iPhones to connect to 3G networks. The only time I've really been somewhere where I couldn't access the Internet at all was in a remote area of Maine, where even 3G connections couldn't reach. The only thing that worked was the GPS, which works off satellite. Once there is practical satellite-based connectivity, then we will always be connected, all over the globe. Do we really want that? Hmmm...
