I just placed my order for iPod Nano and thought I'd put my reasoning on record for those who are considering a move to Nano.

I've owned a 3G 30Gb for 2.5 years now. I really love the product and it has served me well. But it has its shortcomings. I originally bought it with the intention to keep most of my music on it. I quickly learned that fitting 60 gigs (83 gigs now) of music on an iPod isn't gonna happen any time soon. I also realized there's no need for this, since I rarely take 44-day long trips where I have no access to my computer.

Also, the form factor of the "normal" iPod is too big for me. I can't really fit it in any non-jacket pocket, and I hate the geeky look of my belt-clip at the gym. And the iSkin I have adds to its bulk, although it has kept my iPod looking like brand new all this time (should get a decent price for it).

But my biggest complaint has been the battery life. Most of my music is 192kbit (ie. big files) and the hdd has to spin more than with the usual 128kbit files. I barely get 3 hours of real use out of mine. Of course, I've had it for quite a while now, but even the original 6 hours or so was too little. I would have to conserve batteries when I'm travelling/flying which kinda defeats the whole purpose of owning a portable music player.

So, I am moving to Nano. I'm calling it an upgrade. 4 gigs of music gives me 600+ songs / 2 days worth of music with my bitrates which is plenty. I can tuck it in my jeans or workout pants pocket. And best of all, I don't have to worry about batteries dying on me on long trips.

Damn, that turned out longer than I expected. What were/are your reasons to moving on to Nano? Or why aren't you?
