Features of the Imac are Led black-lit Displays or HD video experience, faster processors, wireless keyboard and mouse ( uses batteries) isight camera, that comes with a tool called Photo Booth, and better Ports. Like other Macs it includes a music software, iMovie, a movie software, a search engine, iweb creating website app, calendar, Ichat, mail software, a DVD making widget, photo software, iTunes, and Quick Time Player. If you don't believe the Imac can do this well I have one, and I search on Apple.com too.

Yes, but a better choice for a student would be a MacBook Pro. It is portable and can be carried from classroom to classroom. It has all the features of an iMac.
Yes, if you have the Macintosh version. The Windows version will not run on an iMac.

The Apple Imac is a good laptop with many versions available to suit each customer's needs. They do not play CD-roms but have a lot of similar features to other laptops otherwise.
Yes.
Who told you it had no USB ports? Of course it has USB ports. The iMac has 4 USB ports, 1 Firewire port, 1 Thunderbolt port (2 on the 27" iMac), 1 Ethernet port.
8 GB of Ram is standard in all new iMac's. They use 8 GB because it is better than 4 GB.
No, you can only get that discount on a new iMac not a refurbished iMac.
The original iMac was the G3 which came out in (1998). It was followed by the G4 (2002), then the G5 (2004), then the Intel iMac plastic version (2006). The 5th iMac was the aluminum iMac which came out in (August 2007), followed by the iMac Aluminum Unibody (2009). The newest iMac is simply called 2012 iMac and it came out on November 30, 2012.
There is no "iMac Air".
An iMac is a computer, but a computer is not necessarily an iMac, so they are not the same thing.
