"Use Windows 10 on your iPad." It sounds good but then there is the typing. And then you're carrying an iPad, a Kangaroo, a portable keyboard, and 3 power adapters, like a post postmodern pack-mule. Not so svelte now are we? (Did this Kangaroo go directly on the lust list anyway? Of course it did.)

The @kangaroocc is as thin as a package of post-it notes and has a 4-hour battery life. Very cool concept to push Windows 10.

To me it looks cool, but for a very small niche. If you really need windows for a few things - and only very few things - but don't want to carry around a Windows laptop for that, it's certainly useful. For most things presented though, I don't see anything it can do that a phone or tablet can't. You can't use it on its own (needs at least a display of some sort), very short battery life, low power (as a desktop PC)...
