It's my second Mac Mini. The first was a G4 running OS X (10.4). Durable. Bought it in 2008, and sold it in 2013 on eBay. Went to the dark side with this newer one. It has an Intel processor in it. Runs great. Got it reconditioned from Apple. Had a G4 tower before that. Heavy sucker. I like lighter as time goes on. Apparently the new Mac Pro has the ability to display 4 monitors, or something crazy like that. Xeon processors, and hundreds of Gigs of Ram. Nuts. I remember paying retail for my Mac IIsi. Expensive, but cute. I remember when a 5 megabyte hard drive was considered unfillable. Regards.
