I disagree. I think the Playbook is the most promising of iPad's competitors. Certainly technical hiccups are common for such devices, Apple included, and I don't think anyone would consider it a deal-breaker that a few devices needed to be recalled so early in a product's lifecycle.
That said, RIM should have waited a little longer to bring out a more polished product. Still, if they do get a lot of the kinks out quickly, I think the Playbook might just be one of the survivors.
Bad start but not necessarily game over.
it's half the size as the iPad, but the same price, and requires a Blackberry phone for blackberry email, and they don't have a way to write natives apps, but rather rely on running their competitors apps. Is that really the best competitor?
