Apple iPod nano 2nd Generation Silver (4 GB) MP3 Player

I have had this Ipod for about a year now. I got it for christmas (but I actually got the RED one, product red). I have the 4gb model. I got this because my old Ipod (first gen. if i'm not mistaken) was falling apart- the buttons were responding poorly, the screen was randomly showing black vertical lines when the light was on, and the batteries were losing their capacity. I like my new one because it holds a LOT of music. It is almost the same storage size as my old one. (my old one was a 5GB). The batteries last a VERY long time on a charge. When the batteries are low, the battery indicator turns red LONG before they go dead. I use it about 1 and a half hours every day, and I can go 2 more days at least using it that way on low batteries. It has it's problems though. if the track I'm playing was imported from a CD that was scratched, in such a minor way that would have very little effect on most any cd player, or the computer for that matter, On this Ipod ( dunno if other Ipods have this problem) the slightest glitch in the track will cause a total meltdown. THe Ipod will stop playing and the screen will freeze, and I have to hold down Menu+select for 15 seconds to "reset" it. I have alot of CD's that are scratched, but my old portable cd player could play anything that hadn't been dropped on a sanding belt. Also, the batteries cant be replaced without opening the whole Ipod, and u risk damaging it by doing this. Rechargeable batteries eventually lose their capacity. This hasn't happened to me yet, but keep in mind that in average usage they last about 2 years, maybe longer if you take good care of it. I always let mine discharge completely or at least let the batteries get to "the red" befor recharging the batteries, and I've had it a year and a half and havent seen any signs of it losing its life yet, so I reckon they're doing pretty well.
UPDATE JAN 17- Well, it happened. the batteries gave up the ghost and I had to send it in to get them replaced. I used a 3rd party service, which was cheaper, but it took forever to get it back. If you plan on just buying CDs and "ripping" them, or buying music on line from a copyright-protection-free service, and you want to avoid rechargeable battery problems and replacement costs, a better solution would be to just buy an MP3 player that takes AAA batteries-or just using a portable CD player, because most downloaded formats can be "burned" onto a CD-R in normal music CD format, which will work in most, if not all, CD players. I've never had a CD player fail to read a burned CD. Of course, the Ipod Nano is more compact than AAA battery MP3 players, and has more capacity than MOST of those AAA battery ones, so decide what suits you best.
