The USB link is easy to use, and is the link to buy if you've got USB ports. While you can't transfer files using TI-GRAPH LINK software and a USB link, you can still use TI-GRAPH LINK for ungrouping calculator data files and viewing or editing BASIC programs on your computer. Then you can transfer files using TI-Connect software, which is more user friendly anyway. Indispensable accessory for your TI Graphing Calculator!
