I have a friend practicing for his Diploma (and LRSM; he's only doing the Diploma because, having prepared for the LRSM he found that his existing qualifications aren't acceptable as he had thought) on a Yamaha P70.
I do most of my practice on a Roland FP2 (especially after 11pm, with headphones) but some on a real piano which won't stay in tune for more than a week or so after tuning and on which the action is kn******ered.
Yes, they are different, but providing that you can get onto a real piano from time to time I don't see it as a problem.
I second what Robodoc has written...of course nothing beats the real thing but yes, it is well possible to learn on an electric piano keyboard and do fairly well too!
I must also say that the ABRSM would accept you to do an exam on an electric piano keyboard (if you look at the bit where they talk about 'special visits' exams, they would accept the place hosting the exam to have an electric piano keyboard if they did not have an acoustic so long that it sounds similar to a piano, well, can't remember exact wording, you can go and have a look it. But many of us go to an exam centre to sit our exams anyway). And yes, would do you some good to play with the real thing now and again (even if only during your lessons).
