Raspberry Pi computers

I cant wait to get my hands on some.  This tiny little computer will be great for so many projects.  The possibilities and fun are endless.  As things get smaller we can incorporate computers into more things.  We can take large out of date electronics and insert these to get them up to date and with in a reasonable size.  There are limitations to the operating systems that can be used or the drivers or accessories that can be used. And there is a barrier to entry on the level of geek it takes to appreciate and understand or figure it out.  But in the hands of the right people I see so much good down the line.
