If Apple is seriously considering this I hope they do some research into recent switchers. I was a PC guy all my life and used to laugh at Apple and their products in the 90's. My MP3 collection was growing and I decided that I wanted to go ahead and rip all of my CD's to MP3's and needed a program to rip them and mange the library. I'd heard good things about iTunes and when it was released for Windows I tried it and loved it.
I loved it so much that after a few months I bought my first iPod. I had nothing but good experiences with the iPod and iTunes and then when the iTMS came online I tried that and really liked the experience too.
When the Mac Mini was announced it was the perfect fit. I didn't want to shell out a bunch of cash for a higher end Mac because I wasn't sure if I'd like the Mac experience. Needless to say I loved the Mac experience and I don't think I'll ever go back to a PC. My G4 Mac Mini has worked like a charm and I'm still using it at home today. It would be shame if they got rid of them.
Yes, since the switch to Intel processors it's possible to install and run Windows on a Mac so the more tech savvy switchers could by a Mac to try OS X and then install Windows if they didn't like the experience and hang on to the hardware, but there are lots of less tech savy users out there (like my parents for instance) who I've convinced to switch to a Mac and to do so by purchasing a new Mac Mini when they buy their next computer. They wouldn't shell out the cash for a higher end Mac if the Mini's are discontinued and they don't want to buy a refurbished or used unit. They want something new, that's lets them do the basics (word processing, browse the internet, send and receive e-mail, rip their CD collection and burn mixed CD's) plus all of the multimedia things that iLife let's you do (manage digital photos, etc.) and they want it to just work out of the box. The Mac Mini is the perfect system to entice less technical switchers. Even if it's losing money, I think if Apple did some research into switchers they'd find that it's a loss leader. It certainly was for me. If not for the Mac Mini, I wouldn't be a Mac user at all. I'm also now the proud owner of an iPhone, which I never would have purchased if I hadn't switched to a Mac first.
I could justify a $300 dollar MP3 player when I bought the iPod because it was large enough for me to carry my entire MP3 collection and navigate through it on the go with ease. There's no way I could have justified $600 on the iPhone without experiencing OS X and Mac hardware firsthand. I bet there are a lot of other users out there just like me. Drawn in by the iTunes / iTMS / iPod, made to switch thanks to the Mini and now own some of the more expensive gadgets and/or have moved on to a higher end Mac.
