I have a mid-2011 27" iMac, which I love, except for one tiny thing. While it does have Thunderbolt (which I currently had no devices for) it only has USB 2 - NOT USB 3 like the newer iMacs have! It's hard to justify getting a new iMac this soon after buying my current one, but I really wish I had a better solution for transferring photo data from my camera's CF card. Currently I have an older Epson Printer (RX600) with a built-in CF Card reader. The USE Connection of the printer to the iMac is USB 2. The card reader works but it is painfully slow when loading images from my CF card using Lightroom. Most of the newer card readers are USB 3, but this variant of the iMac doesn't have USB 3, only Thunderbolt ports. I can't find any CF card readers that are Thunderbolt, but I've heard there are USB-to-Thunderbolt converters. Question for any fellow iMac users in a similar situation - are there any good solutions for this short of buying a new computer? Does anyone else have a mid-2011 iMac with USB 2 and TB ports who have figured out a solution?
