Nice start and definately an improvement. But shouldn't the long term goal be way longer support?
I don't want my TV,NAS,Router etc to be only secure for 2 years. Maybe just because not a lot of bad things happened so far doesn't mean they aren't to in the future. A world stuffed with vulnerable Linux devices that soon posess a lot of computatinal power and storage are a big target for spammers, crackers and spies. Especially with XP dying and Windows getting more secure.
In my perfect world embedded devices would standardize more so that some kind of automated update system would work and each device would pull updates automatically (with enough checks and backups so that very rarely something breaks)
It is not easy, but definately possible. But I guess consumers would need awareness to vote with their money units to really make it happen ;-(
I would love to see awareness about community supported devices grow. There are a few communities that provide easy updates. Most of them are way too hard for your average guy, that would need to change but OEMs could help there too. If they don't do more they are at risk that someone like Apple might come in and just improves on the current state of things a bit, but offers better support with new features for years. All the OEMs need to understand that they are selling products that are mostly defined by software now.
