As an alternative, I wonder (for Ipad 1 users) if we can get to a point where there is a decent browser that will run the plugins (or at least mimic them) such that dishanywhere.com can be used. Puffin is getting there - I was able to run a few on-demand movies but (of course) not watch live TV given the lack of sling adapter plug-in.
Meanwhile, we have a few apps for movies - Epix HD, Go HBO, Max Go, etc. plus some live sports apps - PAC12 and maybe ESPN at the end of the month. Plus you can still convert and send DVR content to iPad via the new Hopper.
I understand the frustration in this thread - Dish pimps the sling technology for iPad but that is clearly not all-inclusive. Add to that the lack of announcement/communication. Honestly, though, I'm not sure what we expect to happen - I doubt anything would make Dish concede to reactivating the old version for iOS 5, even though iPad 1 could certainly handle it. Hope I'm wrong there, but I don't see it happening.
