To quote a month+ old post I agree. Just watched the video today and I love it. There is so much potential there, especially for the standard user and proper business types.
Apple seems to be moving away from a proper computer OS (OSX) to a mobile version, with some saying they will scrap OSX all together for iOS. Microsoft are still keeping separate systems, their phone system and their tablet/productivity system whilst bringing it up to touch standard. With the increase of cloud computing and things like WiDi I can see a new future for most people.
Most laptops, even business ones don't need to be massively powerful for what they are used for (Office, internet, occasional flash/basic gaming and viewing/basic photo/video editing). Why not have a tablet with a full operating system and full programs that also functions as a perfect mobile touch system? Just imagine for a second....
You get up in the morning, grab your Win8 tablet and catch the train. You use the touch interface to check the news, watch a video, look at a few photos and play a few basic games to while away the time (like you would with an android or iOS tablet). You walk into work and drop it onto your desk, onto the induction pad, press a couple of buttons to project a second screen onto your monitor using WiDi and pair your wireless mouse and keyboard with the device... Away you go with your work for the day, full versions of word, excel and any other windows program you want (using the tablet screen as a giant touch pad/secondary monitor if needed, or jut moving it out the way)... You head home, on the train you realise you forgot to do something so you pull up your work you were working on during the day and sort it out, whether that be word, photoshop or another program.
There are plenty of other permutations for everyday users, you could easily have a dock, like the Acer Transformer for when you need extra battery or a keyboard during the day, or just storing your tablet at the desk... Wireless storage for videos and other such things.
IE for most users it can be their primary machine (which is now generally a laptop) and their small entertainment device, rather than having two devices to do the same job... The possibilities are endless, to quote the recycle advert...
I assume as well that by the time of release there will have been a lot of work done under the bonnet and a bit of a rework of the standard desktop view as well. I'm sure the grey theme will still be available for you if you still rock the 95/98/2000 look... grey... what a colour...
