But seriously, no, in a few years most consumers are gonna be exactly where we are now, sitting in front of a good old desktop and/or laptop.
No one minds the occasional innovations like seeing gadgets go from a side bar to the desktop. But to strip away more then just the familiar desktop gui for a Tablet type simply doesn't go over well with most! Besides that there are some other things that have been noticed as well showing this will be a different animal to work with in contrast to how things are done in Vista and 7.
please tell me how to do my work with say a 60 cm monitor and only touch input.
Apart from the fact that my arms would get really tired quickly I would't even be able to REACH the wretched thing ( and I'm not small either !!) -- I'm not sitting with my nose almost touching a screen that size -- and if I did I'd probably have to wear glasses as thick as Milk Bottles after two or 3 months.
So long as "traditional" work needs to be done you will still need "traditional" methods of input -- and that means (usually) a keyboard and a mouse. You can enable some vocal commands on some devices --but I suspect you'd be very unpopular in a a busy office yelling commands at a screen.
For me the tablet is a "nine days wonder" device that won't I suspect be around for too long
if I need that type of stuff some of the better smart phones can do evevrything and MORE that a tablet can do. - With a 32 GB micro REMOVABLE sdhc card too you can store almost as much music / audio books and even a movie or two on a phone and the new Galaxy III s has a screen that's just about OK for watching say a movie on a train / plane without having to get a computer out. - Plenty of android apps for playing AVI etc.
The only time I touch any screen is when using an lcd cleaning solution and the wipe pad for removing the cleaning solution along with any dust or dirt. I think after pushing an index finger into the screen long enough most displays would end up with a hole in them!
My cell phone has a 16gb SD card in that and holds a music library. The only thing I have to dig out is the blue tooth head phones for listening or taking calls(good sound quality but not so good on battery charge). Even that has the option to browse, check your email, social networks, etc. for a pocket sized hand held that's not as evolved as a smart phone even.
W7 already has support for touchscreens where the need is present. I think is saying: "You can still use 8 on a desktop. But we designed 8 for the other markets mainly. Our devoted fans will still buy into it however." right!
With 7 being a solid desktop OS MS could now play around in the other markets in order to sneer at Google and others by showing they can jump in there as well.
For desktop the typical user not only will want to find a work around for Metro but now must learn other things on how to set things up for 8 since a simple bios setting change trashed the RP install making it unbootable while 7 successfully started right up and installed the two OS drives with a restart required. It's not going to be the Vista to improved 7 OS type of upgrade into 8 just like Vista saw a large gap between that and XP in how things work.
The plus sides are few at the present with an improvement in security as well as IE 10 being a smoother running browser then IE 9! The downsides however are taking it's tolls on the majority of typical desktop users as well as a new learning needed for what other unseen changes have been made. It's a different ball park that 8 takes you to!
