There’s an interesting post on Trusted Reviews where Sony Ericsson Global Marketing Director Fortuné Alexander reveals that they are moving away from using Sony’s proprietary Memory Stick Micro (M2) cards in favour of MicroSD in its handsets.
Proprietary memory cards are slowly going the way of the Dodo, what with Fujifilm switching to Secure Digital (SD) instead of staying with xD-Picture Card only and even Olympus offering the microSD option in its digital cameras.
