Keep or return?

[petaks01]

Have to get the unit first, placed the order a few hours ago

But I feel that it may be easier to get used to it since it has so much similarities with the 48.
Currently getting used to using the emulator and so far everything has been easy to
understand even if some features have changed and/or moved.

Keyboard Scan frequency?
Sounds like it is hidden somewhere deep in the system, any guides available?
If I don't change it, what will I miss?
