Got my Touch Pro coming in a couple of days and was just thinking over things.

First thing that came to mind... Since the whole back cover comes off for battery and card access, any possibilities of replacement, uniform backs... I'm not overly fussed on the faceted style and would much prefer a flat, rubber textured back. Any vacuum formers out there...?

Second thing. Does anything like this exist... Imagine if you will a standard micro SD card but instead of having memory inside it is basically a plug. From the back of it comes a flexible ribbon cable that attaches to a slim hub that in turn takes at least 2 micro SD cards (3 or 4 would be even better). Is such a thing possible? Just thinking since 16GB cards are expensive whereas 8GB seem quite cheap, the ability to plug in multiple cards but the controller card presenting them as a single storage device or possibly virtual directories within a single device would be great.

Also, putting the two ideas together, since the Touch Pro back is a whole unit and could effectively be made deeper (if someone decided to make a custom case back) then, since the Touch Pro micro SD card is beneath this cover then such a micro SD hub could mount underneath it...

Ho hum, all this waiting...:D

Why not go the whole hod and have a replacement back that is a normal SD card reader?

Assuming microSD cards are the same as SD cards, that means there is a chip select (CS) line which needs to be held active when reading and writing to the chip, this is used to select the memory card, knowing this means it would not be possible to have multiple cards as you couldn't switch between them without an extra IO port available on the microprocessor (and I'm sure HTC aren't releasing the schematics any time soon).

Was just thinking aloud...

With regards the multiple cards, was thinking that the electronics in the 'plug' would take care of mouting the individual cards and presenting them alltogether as one to the device, i.e. the device wouldn't be aware of anything.
