Well, got the E-50 today. It is a beautifully laid our board, with everything in reach for live play. Here are some pros and cons (IMO):

- Small keys & suspect keypad (but time will tell on the latter)
- Lighted buttons are very pretty, but not sure if they are for the long haul. I guess I'd need some reply from an EM user, because they seem to be the same
- The speakers are extremely weak - I was disappointed. The enhanced bass just makes things noisy

- The styles are to die for - just absolutely fabulous
- The overall sounds are very good, but the pianos are a bit disappointing, just like Ian claimed
- The variation and fills are the best I have found on any Roland product, smooth and useful
- The touch screen is vintage VA series and with the extra panel buttons, it's a welcomed feature in my book

This is just after a couple hours. I am hooking up to my home stereo to check on the pianos and overall power. Is it a keeper? I really love it so far
