some GPSs use a real alltimeter that can be used, but neither the legend C or regular legend has that...
according to garmin, the legend lasts 18hours on batteries and has 8mb of memory, and a serial connection port
legend C has 36 hours of life on one set of batteries, 24mb, USB port (faster transfer speed for data, maps, etc..), auto routing (turn by turn road navigation), and color display... and overall i think it's unit itself is a bit more condensed.
according to someone on another forum when i asked about buying a GPS, the regular legend takes a bit longer to aquire and everything, since it's older technology as compared to the C for instance...
if you want to use it for a car in the future, the C does have turn-by-turn navigation... also be forewarned, with the handheld GPS units, you do have to purchase the maps (about 75 bucks) for yourGPS, then you upload the maps from your computer onto your GPS, and thats where the memory comes into play, the more you got, the more maps you can store... i havn't purchased any maps yet, i've only used my GPS on the road to track speed, distance, and to see how far away i was... i will buy the maps later... right now i've been using it for geocaching.
