Someone asked about this once before, and I did a demo of it back then, but I wasn't too thrilled. Yes it does provide all the charts for you in a very handy space, but the charts are far outdated. The ones I fly with on VATSIM off of www.myairplane.com are all dated august 4 2005 - sept 1 2005. You'll never find something as current as that in the package =). Not to mention, the above listed chart sites are free!
However, one reviewer made an excellent point about this package, that it now eliminates the problem of you losing charts, forgetting where you put them, having to file them yourselves, etc. That is a problem with me, since I fly so often and my charts are constantly out of order! (I really should just get one of those pilot binders to store it all in).
So are you looking for good organization? or up-to-date free charts? Most of the reviews I saw on this came down to that point and most of them agreed that the charts would definitly be worth it if you invested the money, but that if you didn't invest it it's no biggie.
