Considering that Maemo already has got some traction with people all around the world, it might be a good idea to promote it further by selling Maemo Merchandise. This would also satisfy Maemo's fans/well-wishers in getting those t-shirt which they only currently dream of :)
The Maemo Merchandise Store (MMS) can start with the regular common stuff like T-shirts, tea/coffee mugs, water bottles, usb drives, caps, stickers, etc.
This can be done either by Nokia or by someone interested (or experienced in this stuff) from the community. Either may choose to do this for a reasonable profit too.
Throw in your votes if you think this is well-worth it. Enough votes might actually turn this into reality!
