The BlackBerry PlayBook is supposed to ship with Flash and Adobe Air support. It will also allegedly run Android apps and BlackBerry Java apps, both through software emulators.I'm not a BlackBerry fan at all, but I have to say that they've done a good job of positioning the PlayBook as an intriguing mobile swiss-army knife of sorts. It also has a 7" screen so they've given apologists a built-in out to say that it's not directly competing with the iPad. The real question is how good those app emulators are going to be. (My expectation is that they'll be OK but not great.) They've certainly spent a great deal of time preparing the product for launch, which is an encouraging sign. They've announced April 19 as their launch day.I bought a 3G iPad 2 on the day it came out and I'm working on making it my primary mobile computer -- basically a "leave the laptop, take the iPad" project. It is going more smoothly than I thought it would. I was concerned about the lack of Flash at first, but I have been somewhat surprised to discover how little I miss it. Maybe that's just me, though.The only place that I've really run into roadblocks is in trying to wrangle files, perform basic functions like document sync and search, and making those documents available across multiple apps. I understand that Apple's position has been that the iPad is a "post-filesystem" device. But at the same time, they've gradually given developers a set of very rudimentary tools for spanning application silos. As a result, there are now a bunch of completely proprietary workarounds that will allow you to sync/transfer files only between certain groups of applications, and often only in one direction. It's a pretty big mess. I'd love to hear how y'all have worked around this problem effectively using iFiles, DropBox, ReaddleDocs, Goodreader, EverNote, or any other combination of apps and storage solutions.The big iOS 5 rumor is that Apple is building in centralized support at the operating system level for streaming and syncing from cloud-based storage. That's the right way to do it -- at the OS level -- and if done properly it should provide a solution for these issues. But it's probably about 6 months off. It could quickly make MobileMe worth buying, though.
