Oddly, contrary to some reactions around the net regarding updates and bugfixes becoming commonplace in consumer electronics, many posters in the thread are encouraged by the indication Toshiba will provide frequent updates for issues discovered by the community. This isn't that surprising when you think back to the many problems early adopters often have to deal with without an official response or fix (anyone remember many of the early DVD players? Ouch.)
