I have a similar situation (linux server for work and Macs for everything else). I manage media through iTunes, stream through two AppleTVs, and use MacBooks, an iMac,and iPhones. Newer Apple products don't seem to have the longevity that older ones do (my iMac is circa 2007). I'm not sure I make enough money to afford upgrading my Apple infrastructure on a two-year cycle.

I've also noticed battery life in the iPad has degenerated, and it takes a looong time to recharge. That's another new trick.
