I don't usually go very opinion piece - but I'm going to have to here. Why should you have to buy another console just to keep a feature? Of course, sony wanted to get rid of otheros as quick as possible (read: security). Costs are a very thin, but worthwhile explanation why it was pulled from the slims - but not the fats.
What's worse, since content and technologies evolve, the legal system can't catch up. Honestly, go up to any 40-60 year old, ask them about new technology, how stuff works. I can tell you that a large majority of them would be clueless. Now, use a much smaller subset of those in the legal / political systems - and your really screwed.
Old laws don't jive with new tech, (not even going on about pending legislation), but simply put - removing the feature strips you of, the feature, and staying on 3.15 cripples the rest of the system. No PSN, no new games, no new movies etc.
Buying a new PS3 is the easy choice - but it should not have to be. Now, if you happened to upgrade, the only way to go back is grey area, which is ridiculous!
Going to end my rant now!
