On my last trip to Kenya/Rwanda I used a 12" laptop and external drives, also holding a couple of Nextos in reserve.
I tested the Hyperdrive UDMA and obtained 300GB of files downloaded at 35.8 MB/sec. to an SSD on one charge. Unfortunately the ND2700 is only getting 120GB at 30 MB/sec. I'm not too thrilled about the $400 cost of the 2730, especially as it is slow with SD cards and does not support OTG. I guess it's about time to order one and test it.
