You'd be correct if you were referring to companies with an established track record for delivering products. These guys have a long road ahead of them. It's a small market with other entrenched competitors which makes it tough to raise money to hire a bunch of engineers. As a result the principals have to do everything themselves on a shoestring budget. They will invariably be late and provided they can get the thing working sometime next year it will still take another year or so to iron out the bugs and make it reliable. Cool product, hope it works but it's still a high risk venture.
