Does the WOW Ultra product feel like an updated product that WOW cares about?
Yes it feels and is a current system. Its nothing like the old SA boxes. IMO the only way you can get a "better" system is to make your own.
The first rev had some VPN issues and slow menus. A recent update reportedly has cured the gateway issues and the menus/guide are faster. WOW's site has a series of youtube videos on it so you can get a feel for the UI.
