Good and bad in the same time
I do use Windows 8. I have to. Regardless what people say, Windows is going to exist masivelly on the business side. Because it owns it. Regardless of the numbers, I don't think that the PC is going the way of the Dodo. Because we still need to work, write letters, use multiple displays, program something... whatever. You can't have that with a tablet. I still need the possibility of adding a keyboard and a mouse. Ah... when I want to disconnect, I can go on the web. But how many of us are doing it? I take the train everyday and I watch people with tablets or smartphones - they play or read some newspaper. They don't work. The ones that work use laptops, thank you very much.
And the application store? Who needs a million apps? I have a smartphone (android) for a long time here, and I have a few games (free) and a few apps (free too). Why would this (the number of available apps) be an issue regardless of the OS maker? I am pretty cool and happy with the options available in Microsoft Store.
Where the buck stops however, is the price. I think that Surface Pro is way to expensive, and it is not going to be a success. And that is the problem in my opinion.
What Microsoft should do is really have two packages - one for tablets and one for PC's. All that SLATE crap is not helping on a PC (or laptop) that doesn't have Touch...
