Just to be clear, I wasn't knocking WRT either. It certainly has it's uses. It's a good device. It's just hard to sell. Selling the iPad was easy. You just had to tell consumers it was an iPhone with a big screen. With Windows RT the sales pitch is much more difficult. It runs a "windows" branded OS, but it can't run traditional windows software. However, it does run Microsoft Office. It is a tablet like the iPad, but it isn't just a windows phone with a big screen (which is what people expect a tablet to be). It connects to the Microsoft store, but it doesn't have a lot of apps.
It's in a category of it's own, and that requires a lot of consumer education which hardware manufacturers don't like paying for. Consumers who aren't sure what it is, or those that aren't comfortable treading off the trodden consumer IT path, likely won't buy it. That has been its problem.
