I was planning on getting an e-yellow Polaris, but prefer 65% boards, so this may change my mind.
Personally, I like the final column, from top to bottom, to be Home, End, Page Up, Page Down, and the right arrow key. So, apart from not liking the logo in the upper right, it also prevents me from having the layout I prefer. Meaning that I would prefer an extra key as opposed to a logo I don't care for.
I don't expect things to be changed for my preferences, but you asked for opinions and responses, and this is just what I feel personally.
I don't mind the logo on the back, however. And I'm interested in what other e-colors will be available.
