Having played Roland and Yamaha boards for years I finally took the plunge and went for the Nord. I use it mainly for live gigs (small to medium sized venues) with both 2 piece and 6 piece lineups.
Pros
(1) The piano and organ sounds are, in my view, unmatched by anything else I have played. The depth of the piano samples - particularly the grands - is superb. Ditto for the Rhodes and Wurlis. Similarly, the B3 sounds (and the ability to easily edit these in a live situation) are fantastic.
(2) The HP keyboard is great. Some will prefer the waterfall version, but as a piano player first and foremost I went for the HP option and have not regretted it.
(3) Portability. This is so easy to carry around, even in the pvc flight case that I bought with it. So much easier than my 88 key Roland.
(4) Program patch storage for quick recall live is a breeze.
Cons
(1) It may be I haven't got the best out of it yet, but the synth patches are not (in my view) as warm or rich as on my Roland boards.
(2) While improved from earlier versions of the Electro, the panel is still not as intuitive as some other brands. With practice and familiarity I expect that this should get easier.
Overall : delighted with my decision, as is my 18 year son who can't stay away from it!
