Had the non expensive toe-in-the-water systems not been available, I'd still be using a PC.
Instead, I'm writing this post on a 27" iMac. Our Point of Sale system is a 21.5" iMac, and my wife, who needed a laptop has a 15" MacBookPro with an external 27" Apple LED Cinema Display. For our server we bought a MacMini server.
This.
I've been using computers since my first PC as a kid, a TI-99. I've been using MS-based computers since DOS 3.0, and have usually run some version of Linux since around 1994/5. My first-ever Apple product was the Newton (I've also been a tablet enthusiast, since, well, forever), but I did not get another until I bought an iPhone 3GS.
I was enthusiastic enough from that purchase that I ended up getting a 2009 Mini. It was mostly because I was curious about iOS development work, and it was very much a toe-in-the-water kind of thing. Of course, it ended up becoming the thin end of the wedge.
The little Mini that could went from becoming a machine that I occasionally used to the little computer that could. First, I ended up sticking my main computer (yet another in a long line of fairly powerful PCs that I built myself) off to one side (it was so much louder than the Mini that I didn't like leaving it on in the bedroom). The Mini became my main personal computer at that point. The Little Computer That Could ended up becoming my most reliable computer, too, when my high end Lenovo tablet running Win7 began acting erratically and costing me a serious amount of lost production time (grant proposals and papers with tight deadlines). I ended up using the Mini more and more.
I am now waiting on the delivery of a top-of-the-line iMac (personal computer), as well as a fully upgraded MacBook Pro (work laptop). I have a personal iPad, and another for work. I'll be upgrading the Mini to 8GB RAM and a larger HDD, and it will probably end up becoming either a server, an HTPC, or something along those lines. The next family laptop will probably be an MBA (wife is a composer currently using a 17" C2D Vista laptop, which has been no end of headaches).
Had the Mini not been available, and an *almost* spur-of-the moment purchase, I might never had made the switch.
