The kobi e readers (at least some of them) are compatible with xc soar. Shouldn't e readers be a smart way to go with the lower battery use and very little disadvantage with black and white? Has anyone tried any other eReaders with xc soar? I imagine most E readers really are not built to operate in direct sunlight, same as phones/tablets but there could be some exceptions.

The dell streak 5" is around 300 dollars now.
