Doesn't appear to have Android support yet.
I guess its popularity will boil down to its catalog and how long/intrusive the ads end up being.
Hulu Plus is not a replacement for Hulu.com. Hulu Plus is a new, revolutionary ad-supported subscription product that is incremental and complementary to the existing Hulu service. For almost all of the current broadcast shows on our service, Hulu Plus offers the full season. Every single episode of the current season will be available, not just a handful of trailing episodes. Now there's never a bad time to jump in on a hot new show like Modern Family (which I recommend highly). From Family Guy to Glee, from The Office to 30 Rock, from Grey's Anatomy to Desperate Housewives, from Parks & Recreation to Parenthood, from House to Saturday Night Live, and dozens of other hits, the best time to jump in on any series is any time, and with any episode, that's right for you.
