I've had my Panasonic TX-L42D25 'smart' (ish) TV for about three years. I'm generally more than happy. What does irk me though is it won't play MP4 movies from my NAS. It will play some formats, just not MP4. This wasn't an issue when I bought it, and it's not the end of the world now. But what annoys me the most is not that won't play them, but why it won't play them. Perhaps I'm doing Panasonic an injustice and there are hardware reasons for the incompatability, but I suspect more likely it's just a software issue which could, if they wanted, be fixed with a simple patch.
In an era where a product's functonaility is limited more by its software than its hardware, one benefit should be that older models can be kept reasonably contemporary via manufacturer-issued updates/patches, certainly for say the first two to three years. Ok my TV is probably just out of that age-threshold now, but more-recent Panasonics have been able to play MP4 videos for a couple of generations. While I could be wrong, I'm prepared to bet that there's no reason really why the appropriate codecs (and other new functionalitlies) could not have been propagated down. The conspiracy theorist in me says they don't do it just because they'd rather we went out and bought a new TV. Surely that's ridiculously wasteful, and purposefully disregards what should be one great benefit of having software-driven devices.
