It's got nothing to do with the tablet keyboard. Creating a letter, doing some styling, adding and editing an image or diagram, using a spreadsheet and all normal 'office' functions are hopeless on a tablet.
I have to agree with Fiscix, the keyboard is a minor peripheral.
I guess that will depend on how good the keyboard is that comes attached to the tablet.
I think Microsoft Surface could be the best of both worlds, a touch screen for when I just want to browse the internet and a keyboard plus all my existing apps (in the Windows 8 Pro version) for when I want to do some work.

I have an Asus Transformer (Android) - with a good (albeit small - netbook size I guess) keyboard. I'll be travelling next week for a court case, and will have the tablet with me, but will only be using it to reference very large legal books; despite having Office (some mobile variations - Quick Office, as well as Kingsoft), I'll also have a laptop - for more heavy-duty work. I'll also have pen & a large pad, as while I've written closing submissions on these devices before, there is nothing to replace pen & paper, particularly as I can't easily format the text on a tablet to make it easy to read while addressing a Judge.
As an aside, as my law books are so large (>10Mbs), most of the ereaders (many paid for, only to find they don't work) I tried can't handle a book of this size.
Tablets have their place, and should have an OS to support them, but I don't expect my tablet to operate the same way as my laptop/desktop/games console: they're different machines, used for different purposes, and I don't care that they look the same or behave differently anymore than I don't expect to find tiles, menus, or an orb on my microwave's controls.
I've tried Win8, but if it's one click from the desktop to anything, I totally missed it; I'll keep using my Win7 licenses for now.
