Bests & Worsts Reviews from Amazon

The NeoCal App is the only calculator I have ever used across three platforms, starting with the old PALM 2's. Make sure you purchase the version with the needed features as there is a big difference between Financial, Scientific, Lite and Advanced. But BEWARE!!! You may find AMAZON's DRM suddenly disabling the app! All Amazon says about DRM is "periodically the DRM token will be refreshed, more information to be provided later". No word about your purchase suddenly being useless until Internet access is available. Where I work wireless internet is not provided so it was a HUGE surprise when the software stopped without explanation except "Internet access required". I would recommend anyone considering purchase of this software to look to another App store that does not impose such crippling DRM techniques.
