Wow! I've been Jobbed by both Apple AND Microsoft.
Bought an iPad 3 and got Jobbed within 6 months by the release of the iPad4, that should have been the iPad3.
Bought a Surface Pro 2 and got Jobbed within 6 months by the announced release of the Surface Pro 3, that should have been the Surface Pro 2. And, the docking station, etc won't work on upgrade.
Be a frigid day in Upper Hell before I plonk down any change on either one of these product lines, again.
Seen several articles analyzing how tablet buying habits are being reassessed due to people using them longer than expected and passing on older ones to relatives. Perhaps that's why MS is switching to a completely different niche with the Surface Pro 3, to try and shift to an unsaturated market segment?
At any rate, I won't be niche-ing along with an upgrade as if I wanted a touchscreen laptop I'd buy one with more capability/flexibility, just like the Mac ultra actually is (and, who knows what the 2014WWDC will unveil next week).
