True dat - I'd add also the IMMENSE array of gadgets, add-ons and accessories that are iPod-only, including car makers advertising that the stereo in certain models comes iPod-ready.
'iPod' has nearly become synonymous with an MP3 Player, almost (well okay not quite but getting there) like Kleenex.
You're absolutely right.
I have a Nokia 5800 XpressMusic/Tube/whatever. Good iPhone competitor. The typing is far superior (I send texts often), and things like the music player are as good as an iPod Touch or iPhone.
If you treat it like an isolated 'thing', they're about the same. However, if you take the entire spectrum of products and services available for the iPod into consideration, having an iPod would have been beneficial, even if the product itself isn't "better". That's what I miss about having an iPod.
If I had an iPod, I'd have iPod integration in the car. I don't care about iTMS or the accessories, since there aren't a lot of things to buy for an iPod touch anyway. I got the case, a useful headphone remote, and screen protector included with my Nokia.
I don't regret my purchase because it's better for things like typing, but there isn't a plethora of products and services to go with it.
