Guess I missed it in the press release, when are these available and how big a mortgage do I need to take out to own one? Or are these like phones now and I really only rent them?

Why does every web site / OS / application always feel the need to change the UI? IOS7 stinks, every new release of Linux feels a need to change change the look of the desktop, etc. Why? Most of the changes are cosmetic and even if not they very seldom improve the usability of the software in question. If you feel a need to be busy, improve something else, make it faster; add a feature *if it makes sense*, etc. I dare you to make the new design a Slashdot Poll question!
