E-A7 is a great keyboard but I ended up replacing mine with a PA900. I prefer to have the harmony onboard, just so much easier to work with. I also prefer the larger screen and once I had the 900, I liked the keys better.

I still think Roland has the easiest "songbook" system-just set everything up how you like it and hit "write." Also nice to have the styles right on a USB stick if you want, although I think the later Korgs can audition from USB. E-A7 has more assignable switches and Transpose and Octave on the left side which I prefer. Korg is a bigger learning curve, but I am getting used to it. Sound wise, they are pretty close IMO.
