I know little about the Hauppauge (or Vulkano). They might be just as good or better than the nomad for all I know. But the OP didn't ask what the best option was; he wanted to know whether the nomad was worth it. BBM3 makes a strong case for the Vulkano.
(And the nomad retails for $149.)
The Vulkano Lava, Blast, Platnium, Deluxe, and Deluxe Pro will do more than a Sling HD Pro + Nomad will for less $$$.
Nomad recordings expire after 30 days.
Nomad will not transcode outside home network.
Nomad has limited programing available including PPV and OTA.
Sling will not transcode to mobile devices.
Sling mobile apps cost $29.99 per device.
Vulkano mobile iOS apps are free for legacy devices.
Vulkano mobile apps are available for iOS, Blackberry, and Android devices plus free PC and OSX clients.
I suspect one key differentiator between using nomad and anything else is the fact that it is/will be available on multiple platforms for viewing, and the process to get each that version on the mobile device is very straightforward.
Put another way...it's simple....it's easy...it works.
The Vulkano is simple and straightforward. Only one button press to transcode to your mobile device.
Vulkano setup is simple. Assign a static IP and open two ports on your router. Done.
I promise I am not a Shill for Monsoon Multimedia just a satisfied customer.
