Single-purpose electronics are great

🍍 mp3 players: You can copy music directly on to them from your computer without having to deal with iTunes hell
🍍 ereaders: You can get one with an e-ink screen whose battery lasts a month on a single charge, and it's way easier on the eyes than a backlit screen
🍍 cameras: More flexibility; photos stay where you meant to put them instead of going into the Cloud everywhere

Please don't reply to tell me about Android for the love of god
