Well here’s a welcome addition to today’s happiness bank: Sony Ericsson is dropping the Memory Stick Micro, Sony’s red hot memory stick platform, for MicroSD. The Memory Stick, if you’ll recall, was Sony’s attempt to rule the roost when it came to memory cards, a strategy that failed so spectacularly that they created an entire sidereal constellation of memory cards outside of the normal collection, ensuring absolute uselessness and incompatibility.

Why are they deciding to move to MicroSD? Could it be them losing billions this year? Could it be because they can’t make a good phone to save their lives? The world will never know.

Sony should scrap the entire Memory Stick line, quite honestly. It’s run its aborted course.
