If you have been wanting to buy Sony SxS Expresscards recently, you will probably have had difficulty in finding any. A severe supply shortage has resulted from the terrible Japanese earthquake and tsunami. Despite Prokit's committment to supporting Sony (we are of course an accredited Sony Specialist Dealer), we have begun importing the S2 Expresscard from Wise. This 19 year old Taiwanese company has much experience to justify our support. Our urgent evaluation of their current top selling product has produced excellent results. Not only are their cards a little less costly than you might expect, but they also feature a USB 2.0 socket for direct connection to PC/Mac without the need for a card reader. They are compliant with the ExpressCard specification.
