Thinness vs upgradability! Such a huge tradeoff.

I really don't see the point in making desktop products super thin (there by making it inaccessible). Thinness is probably one of the last innovation area that customer may be excited for a desktop product. I would hope for better R&D direction in the future from Apple.

This was evident in the Apple stores this weekend, where I saw iMac tables failing to draw any crowd.
