> what's the general need for microSD? I use a USB pendrive formatted with a case-sensitive partition to cache data for an app I use, because it's far better to spend 20$ on a pendrive than 200$ for a SSD upgrade. Given the choice, I'd prefer to use a SD card for that than a USB pendrive, as the USB pendrive requires either a USB hub or a USB pen always sticking out of the chassis.
