I saw a site with a sale on used iBooks earlier today. $140 for a 12" 1.33 GHz G4 with a 30 day warranty. That's a 7 year old computer that can't run anything newer than 10.5, and won't run recent versions of any 3rd party software. I don't understand who buys these.
It still works perfectly as a nice typing machine, it will play your music etc. A friend of mine is a musician and considers getting a PowerBook (!) to run an older version of PureData. The machine is cheap (which matters to him) and still you can get a lot of kick out of it.
I'd rather spend an extra $100 on a decent netbook, mostly because of the warranty. Spending $140 for a piece of hardware that might fry in 91 days feels risky to me.
So what- are you saying that any company that builds products with a strong secondary market or longer shelf life than the category norm should be exempt from maximizing recycle-ability?
