Hello guys! This is my first post... of many I hope! Okay, so I just got my first Mac, I'm studying Computer Science at University and figured it would be a good investment! Now I'm looking to upgrade my current Belkin G 54MBps Router, I don't have £150 to spend on the latest AirPort Extreme although I do want one, so I've been looking on eBay and they seem to go from anything between £20 - £50 for a Second Gen +. Now I know these are Draft N, but is there really any major difference? I have the latest iMac so would I experience any problems at all with an older APBE? Thanks in advance, Bioshox.
