I did a lot of research before buying this watch. Only multifunction watch that has a heart-rate monitor and is also "cool" enough to wear pretty much all of the time (as long as you don't mind wearing a big honkin' watch). I highly recommend getting an infrared USB dongle (if your computer doesn't have infrared port already) for your computer (see http://sewelldirect.com/usbtoirda.asp) so the watch can download the action files and other settings/files to your computer. When you do this, your workouts (aka action files) are saved on your computer for a VERY detailed analysis (more than you'll need, trust me), including cool graphs/plots. If you just want to upload settings from your computer to the watch, then you don't need the infrared on your computer (use the "audio" upload feature). Only major beef: the alarm is not loud at all!! Probably won't hear it if anything is going on in the room at all (e.g. in gym with music on).
