The reason you'd buy this over the Roku, though, is if you have a large library of digital files. The laundry list of supported types misses very little and includes notables such as FLAC, AAC, MKV, DivX, and even ISOs. The small Dolby TrueHD logo on the top suggests that the device will also play Blu-ray "rips" with full-quality sound (although we didn't test this).
