If you can't get to a Windows machine or Mac, low-level formatting
on a digital camera will clean up the card read for NOOBS. After
that, I've always had success with:
unzip NOOBS-ver.zip -d mountpoint_of_SD_card
I think the SD card type sensitivity has gone away with more recent
firmwares on the Raspberry Pi, but they are still very critical of
poor power supplies. The 2 can be especially picky, since it can put
out larger currents over USB than the earlier models.
I do like the Model B Version 2. I'll have to see if it's faster
than the two older (> 5 years) computers I have lying about for
dedicated jobs.
Incidentally, Lawrence now has a stock of the Raspberry Pi 2 now at
Creatron.
