I have spent the last five years not buying an EFB and am once again thinking about it.  Seems that you can get a decent, daylight readable tablet computer for around $2K but if you want one with a solid state hard drive (which supposedly you need if you want it to work above 10K feet) it's more like 5K (at which price I will spend the next five years not getting one too.)  Then there is the eflybook which is some kind of computer with a black and white screen but that reproduces NOAA charts and plates, is daylight readable and doesn't say anything about whether it can be used over 10K feet.  It costs $1500.  Anyone out there know anything about these things or have any recommendations?
