I would like to get an iPod, and I'm eyeing a refurbished 4G monochrome 40 GB iPod with click wheel, dock included, for $200. I know from my friends' experiences that old iPods had a ton of problems with locking up, erasing music, and basically sucking. Perhaps this is related to Windows. As far as I know, new (5G) iPods haven't had as many problems. If I buy this iPod and keep the software up to date, will that prevent the problems? And will I still be able to use the included FW400 connector? BTW, the only features I care about are the two in my questions, so please don't let this become about color or video capabilities.
