Khurt,
If you end up with the ACCU-CHEK Nano, please check out Glooko Logbook -- http://www.glooko.com.  I am biased since I work at Glooko, but with our Glooko MeterSync Cable you can automatically download the readings from your meter into the Glooko logbook app on your iPhone.  From there,  you can take notes, review trends, share, and export as an CSV file.
Best,
