Save space for hardware, especially in notebooks, is quite important: the ports are not infinite, and, though some of us it easy is not the most fun in the world walk by opening and closing cabinets computer.
So if they’re needing a card reader SD, a good choice is the mouse which we found on Geeky Gadgets a couple of days ago.
The original design seems definitely saves space. Its shape fits for right-handers alike, and can read SDHC, SD, MMC, miniSD, microSD and T-Flash.
If you are concerned, its available in store USB Geek for $ 12.
