Just for christ's sake - Why is a tablet not a personal computing device? Why is a tablet POST PC? I don't get the meaning of this buzz-word.
Oh, and what you really should do, please do me a favor and do some internet searches on future Office revisions. With the Metro UI Office will be a charm on Windows8 based tablets.
Aaaah, I forgot. If we believe *LTD* then Excel will suck on a tablet. Meanwhile the *revolutionary* and *magical* Numbers is perfectly suited for the iPad.
You see the logical holes in your argument?
For Christ's sake? I didn't realize this religious war was turning into, uh, a religious war.
OK, I'll try to explain what I mean. Why is an iPad a Post-PC device while still being a computer? PC in this context means a box and keyboard and mouse and monitor. That's the typical setup we are used to for the last thirty years, more or less the lifespan of the PC era. Laptops are merely compressed versions of the same thing since they preserve the keyboard and a mouse-like abstraction for pointing and the screen is separate from the keyboard.
The iPad gets rid of the abstractions. You don't have a device between your fingers and the screen. The mouse is gone and you just naturally use your fingers. They physical keyboard is not needed nearly as much as you'd think, so you get a software keyboard only when needed. The OS is in the background, so you don't have to be confronted with OS ideas such as folders and files. You just use an app, and the app handles the data.
In short, the iPad drops almost everything we think of when we think of a PC. It's a new paradigm.
That's why Microsoft bolting on new UIs to old code bases won't work. It's too jarring, for Microsoft being Microsoft, the new UI will only appear some of the time, but at other times you'll be back in the old Word or Excel menus and the effect will be jarring as you try to use your fingers to manipulate items that were meant to be moused and clicked.
Numbers, in contrast, was rewritten from the ground up to be finger friendly, and it works in the new way. You never, ever, ever see the old way. It's all new. Not just a UI bolted on.
Your final comment about the use or lack thereof of tablets for you indicates your ignorance of what tablets can do that you cannot easily do with other devices. Remain in ignorance if you wish, but the world is going to pass you by. Nobody who experiences what touch UIs can do will ever be wholly satisfied with an abstracted mouse experience again. It just gets in your way.
