We all know just how small microSD memory cards are, and here comes along the EagleTec USB NanoSac microSD card reader which is so small, it looks as though you directly plug in your microSD card into the USB slot. It tips the scales at a mere 2 grams (!) and is able to read both regular microSD and microSDHC memory cards. With hot-swapping capability imbued, you can use this as an impromptu USB flash drive for your portable data transfer needs without missing a beat, and best of all is, you can leave this plugged permanently into your USB port on the notebook without worrying about it snapping off unlike other USB memory card readers due to its insanely small size.
