Nice choice. If it's the M, then you'll have the same engine issues as the M3, but since it's a new car, the crankshaft bearing issue shouldn't be a problem.
If it's the normal Z4, you'll have to watch out for the radiator neck failing, the coolant impeller failing, and thermostat failing. The first two will strand you, while the last is more of a nuisance. Besides that, the engine is solid and is one of the sweetest engines out there.
The car's pretty new, so it's too early to tell what else could go wrong.
From a practical POV, the M coupe has a much smaller trunk because the battery takes up a big chunk. Visibility is pretty limited in either coupe, too. If it were me, I'd get the M. The non-M is nice: it's lighter, has better gas mileage, and cheaper, but the chassis really can handle quite a bit more power. In either case, it's a rare car.
Bimmerfest pretty much has the best Z4 forum around with lots of knowledgeable people (eg. Ron Stygar) hanging out there.
People I know who are very good drivers say that the Z4 is pretty much the best handling car BMW made. That was before the E9x 3-series and 1-series, so that may have changed.
