This is a TERRIBLE idea in my opinion. Apart from the blatant marketing LIES (this will NOT get you free money, you will lose money on the electricity, even the promotional material admits this in the fine print) this only claims to do things that EVERY OTHER computer already does.
You can already use APIs in half a dozen programming languages to do every one of the things they mention in this blog post, and you can do them for less than 5 cents per hour on EC2 (which is $400/year [compared to $400 upfront + electricity], but if you're running it for a year straight you can get it cheaper at places other than EC2).
If this didn't have the magic buzzword of "Bitcoin" in the name and a smorgasbord of people cross-promoting it for reasons I don't pretend to understand, everyone would see that it's just an overpriced, under-powered computer.
