I just picked up the ZEKI SMB at walmart also. I have 3 Roku and the vizio co-star and I can say this is not as popular but it can be. It gives you more option than the roku because you have access to the google play store. The vizio costar has access to the google play as well but I can't get 95% of my apps to install not even by sideloading.
This box gives you a 100% Android feel with the ability to customize the home screen and access the google settings just like your phone or tablet.
So far I can't get the hulu plus but I haven't tried the other modified hulu apps I have yet. I have FB, gmail, my regular email, netflix, plex app which are my main apps up and running.
installing apps could be faster but i'm not sure if it's due to my doing it via wifi or if it's cpu.
The remote does feel cheap but it's not as big and bulky as the co-star remote.
I can see this becoming very big if it can get rooted and then a nice kernal for some OC/UC love.
