By the way, I do have a circa-2008 convertible laptop/tablet which I use for detailed design work. It can do things that a normal capacitive screen tablet is incapable of doing (precise control down to one pixel and hundreds of levels of pressure sensitivity). I need, and I will purchase, a more improved version of such a machine but then it would be around $2000 or more!!! (and I do not need to have a stupid Metro interface on this).
Again, the Metro interface is seriously dated. ICS, which would drive the upcoming generation of Android tablets is far superior as an interface because it is much mover versatile and has already copied and even surpassed ideas of the Metro interface (and I can modify it all that I want). These tablets are going to be in various sizes with all kinds of capabilities and much cheaper than Win8 ones.
So, let me see: If I need a tablet, I have a choice of cheaper ones with a better OS UI. Why would I want a Win8 tablet? I have not heard any argument on this as yet.
