slow...

Looked lovely, as with all Sony Ericsson software, its just sooo slow, and I'm fairly sure its all down to sloppy coding,

stuttering

Its the garbage collector and the 'let the OS decide if you're app gets unloaded' architecture. Designed in non-deterministic behaviour which guarantees no matter how fast the CPU is it will always get stalled unpredictably. My G1 often takes 1/3 sec for garbage collection, affecting every running thread to varying degrees.

Android's core design is unsuited to real time performance. Much better at limping along on inadequate resources than running smoothly.
