I play a digi for reasons of space, cost and convenience. Of course it's never going to be as good as an accoustic but I agree with all the above reasons for getting one.
Because I generally only play very early in the morning or very late at night the headphones are invaluable. You can also put it on harpsichord for Bach, which makes practising inventions a bit more interesting!
The downside is that although the keys are weighted they're still lighter to the touch than an accoustic and the pedal is crap, which means you can get into bad habits. And you're never going to get away from that electronic sound. But then again, they're not as sensitive to movement, humidity etc.
This is why I never play that well for my teacher but what the hell, I'm never going to be a concert pianist so my digital works just fine for me. If I didn't have one I wouldn't be able to play at all.
If you can get an accoustic, get it, if not, a digital isn't too bad for second best.
Of course the ideal option is to have one of each.....
