End of August was last timeframe given by Motorola, they did pretty well sticking to it on the Droid, what makes you think they won't on the Droid X? 3.0 next month or October? The earliest I've heard is end of this year or beginning of next. There aren't any "pure" Google devices I can think of off the top of my head anymore, since the Droid and Nexus One are both not being sold anymore. The Nexus One will naturally get the update first, since Google made the hardware conform to their own standards, but other manufactures have to build their own drivers and kernels for the OS, and the Nexus One also won't run the latest and greatest forever, I'd guess 3.X will be the last official update it can handle, once 4.X comes out, much like old iPhones, it won't be supported officially, also just like the G1. Honestly, it seems like you are really going out of your way to demonize the system, when at the end of the day, as an end user, it doesn't have a whole lot of effect on you. I get it though, we're tech savvy, we love our updates, but the vast majority of end users don't care, hence why Apple can go so long between doing major overhauls. Fragmentation doesn't effect the vast majority of Android users, it has been nothing but a red herring for Android detractors since it was first dreamed up.
Also, I can't speak anything about trial software, as I've never dealt with any, so I really don't know what you're talking about there.
