I'm not sure if I understand why everyone thinks it will be a good idea to put Windows 8 on the Touchpad. Here are my thoughts:
1. Drivers will drive us crazy. There will have to be new drivers created for video, audio, bluetooth, etc. None of these exist currently, so it will basically be like starting all over again. Remember how long it took to get the Android drivers running? Some of them STILL aren't perfect.
2. Since the device is using an ARM chip, only ARM compiled apps will work. It's not like you are going to be able to load your standard x86 Windows apps on the Touchpad if Windows 8 is on it. The amount of ARM apps for Windows 8 is less than what the Blackberry Market has. (which isn't much. )
3. Chances are, we are going to have to completely format the Touchpad if we want to put Windows 8 on it. This removes any possible way of going back to webOS or Android if we want. I, for one, would not like that at all. As far as co-existing... I doubt that would work due to the nature of the file system as it is now.
It's fun to think that this will happen someday, but I'm not holding my breath.
1) hopefully most drivers will work out of the box, since you know they are going to make Win8 arm for a snapdragon SoC, maybe not this exact chip, but a dual-core snapdragon probably, they were also using TouchPads to pilot win8 arm, so if we can get a leaked build we'll be ok. If the drivers don't work and it's too much of a hassle then that's just how it is. We've still got ICS and JellyBean
2) that's fine, but there are going to be so many awesome win8 arm apps, just think of all the WP7 apps plus a lot more, it will be really awesome.
3) Not necessarily. Remember the same thing was thought of on WP7 on the HD2, but what the DFT team did was create a totally separate yaffs2 partition and write Android NAND and WP7 to that, so you could still operate the bootloader to load another OS from the sd card and dual-boot that way. Since this thing rocks 16gb nand, I don't see why some whiz dev couldn't just repartition and format a specific partition for win8 then the bootloader decides where to boot, hence 8 gigs for Win8, 8 gigs for Android, etc... or something of the sort. I think it's possible.
Like you, I'm not holding my breath, but I actually love how well CM9 currently runs on this tablet to keep it only for that, Win8 for arm port would just be a really amazing treat on top if it ever happens.
