Immensely pleased with this little wonder box. I have just upgraded from a ten year old iMac so it is like changing from a Fiesta to a Ferrari! Snow Leopard is a great OS, more advanced than Panther obviously, but easy to understand if you have used the earlier systems. Can't think of any niggles except for having to buy an extra cable as the one supplied by Macintosh does not connect to my new Fujitsu monitor. Thus the fifth star is missing.Mac state than you can take your pick from the available Monitors, so should supply a variety of leads. I found a reasonably priced one at Neet cables. The Mac mini is expensive, but if it lasts as long as the iMac - not dead, but grinding to a halt now - it will be well worth the money. Recommended to enthusiast and amateur!
