What Can I say.... Windows 8 is good ...have it on two computers but I use Stardock's Start 8 to make my computer more like Win 7. However, the start up and shutdown is much faster on my machines than windows 7.

Tablets: Now making my Nexus 7 and Nexus 10 my main work tablets. I bike 15 to 30km a day between workplaces and the tablet beats the small notebook I had for formfactor and weight. Yes I have a bluetooth keyboard that works fine with both Nexus computers and my droid phone. 85 percent of my work can be done by tablet and I only need my notebooks when I print something out in the morning before my workdays. Me thinks the tablet is not quite there but the DAY is approaching every week.
