Funnily enough, having been historically hard on iPod (I had an awesome iRiver H120 which I loved.....then I left the fucker on the plane.

) I am now the (reasonably) proud owner of both an iPod Nano and a G5 80gb video iPod as well.
I have to say, that most my reasons for not buying into iPod have pretty much been resolved.
My new one sounds great (So much of this is in the earphones anyway - my E3C's are spot-on), the battery life is much improved and I never used OGG or FLAC anyway.
I do miss the optical in/out but I can live with it.
As for - as Dub mentioned - being forced to use iTunes......well it's no longer a contentious issue for me, as I bought a Mac mini last year to hook up to the TV and surround sound system in the lounge (amongst other things) and very nice it is too.
Of course, as I had all this MP3 music on my shitty old PC, I ended up importing it to iTunes so I could use that and front row to play stuff in the lounge.
Once I had
already stepped down that path and was using iTunes anyway, it then made more sense to buy the iPod(s)!
I have been Appled by stealth.
