Hi, after using my SD mobile device for a few flights now I have to say that its a really nice peice of kit and works great...............but my one gripe is the screen resolution. If you use the web planning side of SD on your PC the resolution is really nice as its set up to work with the PC screen but on the Mobile device I find it to be quite poor, this is a £599 device so not cheap yet the sreen resolution makes it feel and look like a £70 ebay device. I have been using an iPhone and iPad for years now so am used to really good screen resolutions and high quality devices, surely its not that difficult to upgrade the sofware/hardware on the SD mobile to give a much clearer screen resolution as you would expect to find on a high end device? Even the cheapest of Sat Nav devices have a better resolution!
