I held off getting an iPod for several years. At first, it was because they were expensive and the early models didn't hold enough. After a while, it was more of a rebellion against the trend. They were so ubitquitous, they actually started including iPod interface in car stereos and boom boxes. And the prices never came down. And they still weren't big enough.
When they finally came out with the 160GB model, this was the first model that even had a chance of holding my entire collection. I didn't want to figure out which albums or artists to put on and which not to, so it had to be big enough to hold everything. Also, I bought it with bonus money from work, so I wasn't really spending my own cash. I thought of it as the company buying me an iPod. But I've had it for years now (since whenever the original 160's came out) and man, I love it. It was free, and it's big enough, so what the hell.
