If them or netflix rented gamez as well, I would switch in a heartbeat. Gameznflix is still too slow in my opinion, and their website is hard to try and find movies and gamez on. I usually go to BBI or Netflix site to find up and coming movies and then put them in the GZFX search. Eb games' site is usually how I find out about upcoming gamez.
Slightly off topic, it looks like microsoft will be rolling out a TV and Movie download service in the very near future. They just posted three Jimmy Neutron Cartoons for $1 a peice and have updated the online dashboard to include movie and TV downloads.
