For starters no one would want say Photoshop on their Tablet.
The idea is that developers create apps for them just like they do for Ipad. You don't see Mac apps working on ipad, same difference, MS is just trying to make a single OS that can function on all the hardware varieties. its assumed then that development is now 2 sided for the same OS. those for tablets in mind and those for full desktops in mind except likely the desktop apps wont' work on the tablet i'd assume.
How well it does compared to Ipad only time will tell, for now i prefer ipad but we'll see what the development comunity and OEM's can do with W8 on a tablet.
it already has. didnt you see my desktop pics? they function much the same way. the screen doesnt slide to another but yeah, no doubt a more robust shell will be made after W8's release. But even the shell on my w7, i liked it pretty well. i just wish i could hide it quickly if i want to see the desktop or whatever.
i didnt know we had tiles in dos. all i remember is having to type in commands then later i recall using a menu system. Macs were the first i used that even had icons and wallpaper but i'm sure DOS had that too at the time....but tiles? like Metro UI or something else?
I had a shareware program that did something similar. That did everything I wanted Windows to do, without the bloat. Give me a big button to poke to launch apps :^D Otherwise, I did everything in DOS :^)I actually had a "Tiled" ASCII menuing system in dos to launch many of my most used programs. That I made myself in GW/BASIC 2.1 😀
