I have owned this piano for two years now after having switched from my acoustic baby grand piano and an old upright piano. Reason for the switch was simple, I move around a lot and this allowed me transport my piano in my car =) saving on van rental and cost of tuning after each move.

Feel of the keys:

For the pianos I have tried under £2000 this is the best one for me by miles but it all comes down to personal preference. I find the keys are accurately weighted and touch sensitivity is good allowing you to make use of all those crescendos and staccatos in the music.

Sound:

Basing this on the main voice (portable grand piano); The sound is very good for the price and sounds best when speakers are on half to three quarter volume. Ideally, if the piano is being used in a bedroom for example with carpets and duvets etc that will absorb sound I would recommend using a decent set of headphones, Personally I use the Senneheiser HD-201 which cost <£15 and to me the sound seems perfect for a piano, not quite concert grand or Clavinova but better than most upright pianos.
Other voices will vary in sound quality but I particularly like the flute and orchestra accompaniments which sound very good with the main voice and really enhance the audible experience.

Features and voices:

Being able to record you music, play two instruments at once, play with backing music (can make your own, pre-installed ones or internet) and even learn how to play pieces via a built in tutorial system showing hte music on a screen and guiding you how to play it make this piano perfect for beginners and people who just want a personal piano,
Other features include 500 voices, a lot of these are stupid like gun fire and running water etc but there are plenty of flutes, violins and saxophones etc too. I would say <150 voices are useful and personally I only use about 20 of them.

Connectivity:

You can upload midi files via the USB port at the back and transfer data (such as the music you played) to and from a PC via the same port. I have not tried connecting to other midi devices but it is possible though yet again it uses the usb cable not a normal midi cable, I doubt the adapers would be that expensive but I don't know.

Build quality:

I have had it for two years and taken the stand apart abut 4 times, it is showing no signs of wear or tear.

Midi files:

I mentioned some on this earlier but just to make it clear you can load up to 5 personal midi files onto the piano at a time (note that songs you record yourself playing count as midi files also). Not a lot but you can always transfer the data to and from a memory stick left permanently in the usb slot.

* this piano is capable of playing xglite format/voices =). It can also play full xg but will reduce them to xglite.


Bad points:

Would be nice to have a bigger screen if your going to use it to display music. Although sometimes used as a stage piano its not the most portable digital piano out there. Only a sustain pedal.

Extra points:

32 polyphony - some will tell you this is not enough but after playing the piano for 14 years and this piano for two years I have found no problems with 32 polyphony if all you want is to play the piano with a little backing music or an extra instrument or two.
Don't waste your money on the BASE end Clavinova pianos, this piano uses the exact same technology but for a fraction of the cost (why? beats me)

Alternatives:

The two major digital piano makes are Yamahaa and Roland. Personally I don't like Roland pianos but if you feel Yamahaa aren't right for you then try Roland.
