any regrets leaving e series for omd?

I 've recently added the E-M5 with the intention of replacing my E-5, however without the HLD-6 it is too small, the shutter button feels 'behind' where is should be, and I'm using the 4/3rds lenses but I need patience with the auto-focus. Good thing my subjects are generally static these days. Perhaps it won't be the E-5 that gets sold...

On the positive side, the resulting photos are generally nicer in my opinion.

Perhaps I'm getting too old and should track down a battery for my OM-1 again.
