Yes. You found the difference.

About the e405... Even with a heavy discount to under 200 bucks (here) I only see one feature that could sway me to look at this over the Axim X30. That would be the Voice Command, but having used voice command products, I know it's not something I'd call a deal maker.

The top of the line X30 has Wifi, which at that price is attractive...
