It seems to me that the only thing the Surface RT will achieve is pissing off consumers because of them expecting it to have windows 8, fully functional MS office, a HD screen etc. etc. ...so why did MS release it? Oh yeah, and it doesn't even have either 3G/4G ffs!

One possible reason is that they desperately wanted to have a tablet on the market in time for Xmas sales, so they just threw it together to rush-release something while they perfected the Surface Pro.

I do not know. I do know that the Nexus 7" was so successful that they are releasing the Nexus 10" now! I might get it! 7" for gaming like I am doing with final fantasy 7 and 10" for browsing the web! Oh baby!

Ok Im sorry but I still dont know this.

Whats the difference between RT and Pro?

Up until now, Microsoft only sold software for devices using x86-compatible processors. That worked out well for the last 20 years, but times are quickly changing and x86-based devices are more and more becoming a rarity. Almost all desktop PCs and notebooks still use x86 processors, but all modern devices (smartphones, tablets, media and music players etc.) are using ARM. In fact, already today about 10-20 times more ARM licenses are being sold than x86 processors.

One of the main reasons is that modern devices are battery powered, and ARM processors are significantly more energy-efficient than x86 processors will ever be. ARM processors are also cheaper and require less space and weight, because they can be included in SOC designs, where a single small chip pretty much contains everything the device needs.

Microsoft had the choice: start supporting other architectures or slowly but constantly become irrelevant. They knew the transition would be hard, because the complete lack of software for ARM-based Windows devices means that it will take several years before ARM-based Windows devices will be able to even remotely compete with the x86-based Windows devices.
But it was the right decision nevertheless. They just should have done so long ago.

Here's a good article about it:

Why do you think it will alienate a lot of consumers?

Because people will buy it expecting it to be the awesome Microsoft tablet which has been hyped for months (Surface Pro) and then they'll realise it's shit.

back when Microsoft began the development of RT Intel was far behind in power consumption compared to the ARM processors, but Microsoft still wanted a piece of the tablet pie so they made a Windows for ARM

but now that it's ready Intel has processors available that make x86 viable for tablets..

edit: ok, somebody already explained that .. ok ..
