I have the k4 (nt) also. Ghosting is...well, sometimes noticeable, especially in very bright light or going right from a page with bold print to regular print. But most of the time you don't notice it and if you do it'll clear up in a few pageturns. Or you can set it to refresh every page--that's a setting available. Battery life is very good though touch can be better. If you want a bargain price ereader you can do very well with this one. If you want a "glowlight", then wait.
