The MBr is a $1299 device. I saw an open box deal for $860, which is $440 off of retail price. I think for this price point it's definitely worth it. Though I wasn't looking for a mini laptop. This computer is a very good computer considering it has a very low powered CPU and is as thin as it is.
I think all the analogies are a little off. This isn't a boutique item as that would imply that it's specialized for a smaller audience. If anything a gaming laptop is a boutique item. The MBr isn't a sports car either... it'd be like a Miata if anything... I won't elaborate.
But the MBr is for the type of person where owning a tablet is "good enough" for their uses but they want a more productive tool. It's good for writing, doing some small photo edits and to surf the internet/stream videos. It does all this well for the size of an iPad air... it actually does all this this very well. It's not for a power user for sure... but I think in a few generation it'll be tiny non-pro Macbook Pro for users who can make do with less ports. I have to admit the only time I've used my USB adapter was to back up my HDD to do a restore... which I didn't end up needing because I started over from scratch...
On a side note... I was able to play L4D2 from STEAM with no problems on the MBr using a Xbox 360 wired controller. That'll be nice to kill some time if I'm ever stuck somewhere and bored.
