Could 'Brick' Codename refer to new Macbook or Mac mini?

Everyone (well not quite) is wondering what the new 'brick' is. Mac Rumors say the codename was leaked by the same source who predicted 'rainbow' nanos. 9to5Mac reckon the new Macbook will be 'all about the brick'., whatever that means. It's also been reported that the new laptop will have a glass trackpad. MacEnstein thinks that as bricks can be thrown through glass, then the brick is the 'Windows killer' : 'we feel it is likely that it is simply a name for an upcoming product (or group of products) that Apple thinks will be sexy enough to pull a huge marketshare away from Microsoft'. Someone else thinks it may be a wireless USB hub for the new slimmer MacBooks.

My take is that it could be some sort of modular design that you can add to or build to suit your growing needs. Windows PCs are preferred by many for the simple reason that they are easily upgradable; the only Mac that Apple 'allow' you to upgrade is the MacPro and they start at £1749. Apple could steal a whole load of Microsoft users if they make the Mac mini more like the MAcPro, ie. something that's not already crammed-full and that can only be opened with a steady palette knife (like the concept above from iPhoneSaviour). It could also steal a few million Mac users who are considering a netbook by bringing out an inexpensive MacBook (fingers crossed). A mini laptop that you could attach to a larger hard drive and optical drive when you're sitting at a desk; a bit like the Old PowerBook Duo and its DuoDock. Now that would be cool.
