No definitive decision has been taken yet (major default apps tend to have many integration points and broader discussions are needed before we can make that decision, such as the Thunderbird decision in Oneiric) as we need to kick off the further discussion.

It was noted that Banshee is by far the better UI, but many people experienced significant issues in stability thus making it feel less usable.

Somehow I've managed to forget how to get detailed JIT profiling data
out of mono, so my numbers are imprecise, but on my x200s a quick check
suggests that AOTing the class libraries roughly halves Banshee's
startup time with a warm cache and roughly doesn't change the cold-cache
startup time.
