It will only work on the Early PS3 models with 4 USB ports and not on the Models with only 2 USB ports see related links
Not all USB mice will work with an adapter. If it did not originally ship with an adapter, that you lost and are now replacing, then odds are it will not work. A USB hub adding more USB ports may be a better solution.

Yes: All USB ports work the same way.
if the Dell computer has USB ports, then all you would need is the USB-iPod cable and download/install iTunes. If you system is really old and only have serial ports (9-pin male ports) and no USB ports, then you would need to get a PCI USB card installed into your system. Do not use Serial-USB adapters, as they do not always work.
This Panasonic Toughbook has 3 USB ports.
iPads do have usb ports. You just have to buy an adapter
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.
Have a PS3 that came with 4 USB Ports
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.
