Re: SD cards
We've had an iMac at home for the last 8 years or so, during which time there has been much swearing and gnashing of teeth at the USB ports round the back. However about a week ago I installed a RAM upgrade in it*. While working on the machine I noticed that our fancy apple keyboard (USB-connected with built-in numeric keypad) also features not one but two USB ports - one on the left and one on the right. This is great but if only I'd found them sooner - would have saved years of huffing and sweary words.
*gone from 4GB to 12GB - it's so fast now, it's like night and day
