only 2 usb ports on the front
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.
There is no minimum or required number for USB ports on a laptop. Depending on the age and design of the laptop, it could be anywhere from zero to ten. I have seen only 2 USB ports on older laptops, most of the new ones atleast have 4 USB ports. Netbooks(10" & 11") have not more than 2 USB ports. If in anycase you need more USB ports, you could buy an USB hub for as less as 10$, which will add 4 more ports to your laptop.
Look on the front of the computer, there should be 2 plugs that look the same, thoose are the usp ports.
Buy a USB extension plug in.
Only if it has 4 USB ports and not 2 USB ports like most PS3s
