That was a pretty good preview/review of OSX. I have been using a Mac at home as a secondary computer since the beginning of the year, and as soon as I heard that Lion was going to be more iOS like, I determined right there that I was NOT going to upgrade my system.
While I do believe that your desktop OS and your mobile OS should be extremely compatible, I do not believe they should be the same. I understand that touch capabilities are becoming even more prominent in everyday consumer devices, but to put an OS that is touch centric on a standard style device is a huge mistake in my opinion. I believe that MS is also making the mistake with Windows 8.
I currently have a WP7 and I really love it. The styling, the flow, the ease of use are all there and make it easy to just pick up and operate. It works good on a touch screen, but when you get to the desktop or laptop, I can see it becoming a huge mess.
This is my soapbox that I have been standing on for quite a while now, and I don't think I'm coming down anytime soon. If Windows 8 and beyond are tiled and touch based, then I will be like all the XP hold overs and keep my Windows 7 beyond the EoS. If Apple wants to slowly convert their flagship desktop OS into iOS let them do it, but I'm sure this move will begin to alienate professionals who really want to get some work done. Same goes with MS.
