Just came back to Phonegap after taking a 6 month break from mobile development. They seem to have ironed out quite a few issues.
For one, I finally get to benchmark my HP Pre 3 where, prior to that, any IPK created with Phonegap Build would only output a black screen, thus making me rely on my cheap China brand Android tablet (no fun at all, I tell you what).
Performance, while not overly great, is still decent. The physics template/Angry Birds clone barely runs at 10 FPS but a port of my adventure engine showed great promise (weirdly enough, it was even less choppy than on my laptop with enabled WebGL).
My very first project (memory game) still runs horrible, for some reason. Takes several attempts to get past the options screen and selecting a card takes approximately 30 seconds/card. There's also no audio. This could all be blamed on an older Phonegap release though, since Phonegap Build still builds the app with Phonegap 2.00. Apparently, in order to update the Phonegap version one has to manually alter and reupload the XML
The fact that the LLA plugin is no longer needed kind of saddens me, though.
The broken audio was a nice way of telling me to get cracking on a manual Phonegap install. Now all I need to do is start up Phonegap Build, upload the .zip and wait for the build. The nerd in me just turned suicidal.
