Yep, have to concur with Bose-X. I have tried (I think) most of the popular ones, and I think that Flitemap is the best option for a moving map display on a laptop (although I'd recommend you to think about a pen-driven tablet). Memory Map is also good if you're happy to use CAA maps, but the downside is that they only do maps for the UK, so you're stuffed if you want to go abroad. Upside is MM supports PDA usage, which Jepp doesn't.
The other option is OziExplorer, which, as Fuji Flyer kindly pointed out to me a while ago, is pretty damn good as well .... copyright restrictions permitting, you can scan and add just about any map to it.
