Pros
- excellent European cover (and much further afield as well)
- regular updates, and some very good regional user groups now forming
- good user configurability, including the ability to enter your own procedures should you wish
- solid maps, with all the vital inforamtion, including danger areas and class A airspace, often absent on some moving maps
- dirt cheap!!
Cons
- not always the perfect user interface for use in the air - see Anywhere maps for my view of the almost perfect interface, but it is not too bad
- the quality of the handheld is important. The application is processor intensive and requires lots of storage - for the more detailed maps reckon on at least a 512K SD card
- battery use is poor (not entirely the fault of the software). If you want to use it in the air without external power you will need a high capacity battery - you can then expect up to three hours.
I could add much more - let me know if you have any specific issues.
New and in theory faster maps are due very soon.
