hello i am getting older and dont want to carry around one of my eMac's from my office into the garden downstairs twice a day , so i was looking for a ibook , i know they have some problems like the bad soldering , which isnt one for me as i know how to solder , but i came across quiet a few "usb 2.0 not working ""ethernet not working " on ebay so how widespread are these other little problems and are there more of these little niggles to look out for on the iBooks or may happen
