The iPad – More trouble for flash?

There is huge debate on the Flash’s future when devices like the iPad wont support it, it’s safe to assume that the iPad will become popular by the response of the public, given that most apple mobile devices are indeed becoming increasingly popular it does stick in the back of my mind that i’m specialising in a dying trade.
With the looming HTML 5 beta looking to maybe give Flash Video a bit of greif, I should be wondering if I should be touching up on my PHP, Ajax and Html skills?
