I'm referring to the main lineup (including the very first iPod, the 4th gen iPod Photo, etc.), and not just the ones that Apple explicitly called "Classic". Honestly I'm getting tired of the limited space in my iPhone and modern iPods. And considering also how Jonathan Ive killed the iPhone and the iPod Touch as dedicated music devices, I'm seriously planning to buy an old-school 80 GB model or bigger. Also there are lots of things that can be done on those little babies! Installing a bigger hard disk, an SSD, a Bluetooth receptor, etc. Anyway. Which one do you think was the best generation and WHY?
