I also have a 30GB iPod Photo, and love it.
I'm NOT a huge Apple fan; Mac computers amount to an annoyance for me, and only add complexity to my job (desktop 'engineering' and escalated support), as I support 4000 Wintel desktops and a paltry 80 Macs. As far as I can see, there is nothing my client's Mac users can do on their Macs that they couldn't do just as well on a WinDOH!z box.
However, with an open mind and a desire for an MP3 player, I went shopping, and included the iPod stuff in my list of potential purchases.
I had recently bought a Creative Labs "Zen Micro" MP3 player for a friend, and had about a week to play with it before handing it over. I came away less than thrilled with the interface and the software. I narrowed the choices to the Zen Micro and a 30GB iPod, but after tinkering with a co-worker's iPod, the choice seemed clear. I did spend a bit more on the Photo version, which wasn't necessary, but I do a lot of photography, and perhaps I'll find a regular use for it someday. I figure that the 30GB capacity alone makes it worth the price premium over the 5GB Creative unit I'd been looking at. Other benefits of the iPod versus the Creative unit? The sound quality is noticeably better; the software isn't buggy; it outputs higher/cleaner volume; and the interface ("click wheel") is far superior.
With a 30GB hard drive inside, the iPod IS both bigger and heavier than the Creative unit, but I don't mind at all. One qualm is the shorter battery life; the 'laptop'-style hard drive's moving parts surely help the iPod suck the life outta the internal battery faster than the Zen Micro's microdrive. However, I have both a wall charger (included with the iPod) and a car charger, and I've not yet had the battery go dead on me during extended use, so I'll live with it.
I'm not an Apple convert, but this is a nice product...perhaps the best MP3 player on the market?
