To echo the others: it's very much a niche + enthusiast device still. Though not to as much of a degree as the rm1 at launch :)

If you're not excited about the very limited feature-set, or because it's hackable, I'd pretty strongly recommend looking elsewhere. Much more user-friendly devices exist at similar prices, but they're locked down / run android (so less battery life, various android benefits and issues) / not as thin.
