Windows 8 maybe not aimed at businesses
My thinking is that Windows 8 is not to be replacing Windows 7; I think it is more of a stab at the tablet market. Windows 8 would not be fit for purpose to install on all of your current business PC's, as a support guy I would strongly advise against it! However I think it would be much more beneficial on an arm or intel based tablet around the home. I think it could even be handy in a workplace for managers/IT department. The metro interface would be great for monitoring servers on the go as it will intergrate with all the current Microsoft technologies (SQL, SharePoint etc) whilst sending those all important business emails! I guess the only thing we can do is wait and see.
If you think about what we use PC's for these days you might notice that we are leaning towards tablet PC's and Microsoft has picked up on this. If they are not careful they could blow themselves out of the market entirely whilst Apple takes over with the iPad, with Android slowly catching up. Microsoft can see market trends and this could also be a big factor in their move to touch screen interfaces. Never before have mobile platforms had such weight in the market and this is Microsoft's addition to the table.
I may be wrong but it seems to make sense to me!
