Simple software to show and modify GPS tracks

I have GPS tracks (in gpx format) that I usually use to geotag photos. Is there a simple software to view these tracks (i.e.: not use Google Earth)? A bonus would be simple modification, like deleting waypoints. TangoGPS seems to offer GPS track import only in connection with geotagging for pictures.

Try Viking - you can download and edit your tracks, and also add OpenStreetMaps, Terraserver or DEM layers. It also allows to have georeferenced map layers and some other features.

I've found Merkaartor (in the repos) to be the simplest. But JOSM is the most used and widespread, it's a PITA to find the right version to use.

I'd say give Merkaartor a shot :)
