In response to a Desktop on RT
Now, before I get too involved in this post, I should disclaim that I am not an expert on the subject, and if I ever say anything necessarily wrong about an Apple product, feel free to correct me, as I have never owned an Apple product besides an iPod (nothing against them; I just don't have the money or circumstance). Also, I don't really like any company more than another, except when it comes to Intel vs AMD (AMD's cooler). On with the post.
So when's the last time you've turned on your iPad and launched Pages and said, if not verbally then mentally, "I'm going to do real work, something other than note taking, with half of my 9 inch screen covered by a virtual keyboard." Most people, when confronted with the idea, reach for a laptop. That's because a laptop is naturally more productive and easier to type on than a tablet. And that's not going to change as long as you're typing on the same screen you're using to otherwise interact with the device. This is also my hypothesis to explain why people buy keyboards for their iPad.
Similarly, a version of an office suite made exclusively for a touchscreen is a productivity hindering idea for the same reasons. You don't want to be typing on a virtual keyboard that takes up half or more of your screen and isn't as fast or useful as a separate input device. The most you'll want to do on a touchscreen keyboard is in the web browser, or a note taking app with a stylus.
Now here's the question we should ask ourselves: Which is more of a crutch, having to get out a keyboard for productivity, or having to use an onscreen one? In my opinion, the answer is the latter. Having to get out a keyboard or having forgotten your keyboard may be an annoyance, but I would have probably thrown my tablet on the ground already if I were doing this post on it.
And that's why I don't want a touch based Office. The only use for one I can think of is with a stylus, and physically writing down stuff on it. Otherwise, I'd just pick up my keyboard/mouse attachment and use that. There is really no point to me for having one in the first place.
Now, the Desktop on Windows 8 and RT has some bugs and problems, ones that might confuse you. Apps in the desktop don't multitask with the others. The icons still look Aero. You cant open a Metro app in the Desktop space or vice-versa. Windows 8 can be considered the first of its kind though, and I'll allow it its problems. Fix those in a later release, but don't get rid of the desktop.
