Here's the deal: Windows 7 will have support for plenty of years to come, probably past Windows 9/Next/Blue or whatever they want to call it. NO school or business will be going to Windows 8, and in NO WAY are you obligated to switch over to Windows 8 unless you are just itching for something new. Like I said in my first post, desktops/workstations/gaming desktops/desktop replacement laptops/regular laptops should stick with Windows 7.......if you want to put 8 on your brand-new shiny Ultrabook, or you want to buy some tablet or other touch device with 8 on it, go ahead........Microsoft don't get a crap either way honestly. They will brand this is a success no matter what and will quietly put it down like the family dog if it is as big of a flop as most people think it will be.
I say start bitching when you don't have a choice, but as of right now, you still have a choice. If you choose to invest any time/money/effort into Windows 8 and you realize its garbage.....you were warned. If it turns out to be the best thing since sliced bread, congratulations.
Myself, I will not even entertain the idea until SP1 comes out.....and then, I still don't see me putting it on a desktop. Can you imagine how freaking irritating it will be if you have to disconnect yourself from the mouse and reach out and touch the monitor for anything? For me, it's either/or. Either buck the system and use a mouse/keyboard for everything, or adapt to using touch/gestures for everything. I still think touch/gestures belong on a small laptop type device, tablet, or phone.
