1 - I only post a lot when special events happen and I have some time during the weekends to do so - I have been particularly active for the launch of ML because I am really disappointed with the non-improvements there;
2 - I sincerely believe Apple is seriously considering a merge between iOS and OS X, and perhaps a full-scale streamlining of chipsets when ARM becomes sufficiently powerful. In any case, we should still have OS X 10.9 or perhaps a final OS XI. It won't go further than that;
3 - You should see my post history to realize that, barring a complete Apple disaster, I will NEVER migrate to anything like Windows or Linux. I have converted more than 15 people to Mac (and they are not looking back) and will happily continue to do so because I am still sure of the superiority of the Mac ensemble against crappy Windows boxes and nonintuitive Linux setups. I started using Apple devices in the late 80s and used Macs (a Quadra 605) when everyone else proclaimed Apple dead in the mid- to late 90s. For me it's about the philosophy of the company and the overall quality/clean lines of its products - once this is over, then and only then will I consider switching to anything else
Having said the above, I am totally critical of Apple's current iOSification of OS X, as well as the overall lack of innovation since Snow Leopard was launched. Nowadays, it's all about "optimizations" and inclusion of existing iOS features, while the company leaves behind long-needed improvements in things such as UI consistency, file system, Finder, codecs, video/OpenGL support or even basic visual cues like spinning wheels for loading processes in Mail or Safari.
Worse, we don't see ANY signs of thinking outside the box and coming up with the next best desktop experience for personal computers. It's time for Forstall and Federighi to go, and bring back Serlet and Tevanian...
