While these low-cost machines are impressive for their price, they always seem to be lacking a little here or there. Looking for more 1+ GB RAM (4GB DDR3 is $20 on newegg) and something that can handle the higher bitrate of Blu-ray (regular or maybe 3D), before I will it consider for a serious media center. So far, I've just seen Tegra 3 and Raspberry Pi advertise that level of performance, but I haven't seriously looked. I'd probably also want 1Gbit wired Ethernet (faster & more reliable), but I suppose wireless works.
Better yet, I could just get a Tegra 3 (or newer) smartphone and have a dock attached to my TV. Maybe they will stop gypping the US on phones before I'm up for an upgrade in 15 months.
