Whilst largely agreeing with some of what the other reviewers have said, I must take issue with one or two points.
Firstly, the statement that the routecards are not configurable is simply not true. They are created according to templates which can be altered freely both with the regard to the values they contain (which are individually described in the included help index under 'routecards'!) and even the underlying html code (colour/font/tablecell sizes/included images etc). Cumulative time and distance can easily be added, for instance.
These changes can then be saved in user-defined templates. What the previous comment 'nothing so simple as a file system' means, I have no idea, as the name/path to each file the system creates is clearly chosen/shown in each dialogue box.
When exporting to excel, it is excel's import system that is the problem, not memorymap's format (html is, er, rather popular), but even this is alterable within the excel import wizard settings.
Yes, some of aerial photography is a little out of date, but since its possible to export a memory map route straight into Google Earth, so what? And if all you want is maps, then for the price of a dozen paper versions you get just about every version of every available OS map covering the whole of Britain. I mean you do actually want to visit these places right, not just fly through them on a screen?
With regard to the annotations, its unreasonable to want to enter more than 250 words in a note every 50m and then complain that they overlap on a 17 inch screen. If you really want to add that much information, just use the 'attach file' function to join a text file to the waypoint, and choose to add it as an appendix on the route card. Printing to A4 is very easy, you simply select A4 when you print :>)
Yes there are flaws here, but if you want to never buy a paper map again and you're prepared to spend some time learning how it works (rather than claiming things are impossible because you haven't found the way), Memory Maps is worth every penny. And the help files are actually very clear.
