I'm delighted with this keyboard, I think it is a great entry-level piece of equipment. Maybe in a year or two I'll be ready for something bigger and better, but this is just great for now. If like me you're an adult looking to take up piano again, this is a good place to start - it sounds great, it feels sturdy enough and it's packed with features
Sound quality - the default grand piano sound is excellent, there are lots of other good sounds I like (esp. the funky ep), but I tend to stick to this most of the time
Touch sensitive keys - this is essential (don't consider a keyboard without this feature). The key action is fairly light compared to a real piano - you may find you are not hitting the keys hard enough if you switch instruments.
Adaptor - contrary to what one reviewer wrote, the keyboard does come with a power adaptor
Note that the keyboard has 61 keys, which makes it smaller than a standard piano. In practice I've found I'm able to play almost all pieces, with just a few really low notes unobtainable. This also means that the keyboard is fairly compact - helps if you don't have much space!
Song book - my only disappointment is that the keyboard doesn't come with a song book, without which the 'learning system' is practically useless. But if you register the product with yamaha online, you can get a pdf version and print that(I had to write to customer services to make this happen). With the song book, the learning system is great.
Other great features - I use the built-in metronome a lot, I also like the ability to record each hand separately - so you can lay down the left hand and then practise the right, for example.
