BEST USED in conjunction with a Notes Repository like EverNote. Must be used regularly to achieve significant benefits. Technology works cleanly and easily as represented. The iPad or iPhone work seamlessly as described in the literature. BlueTooth connectivity is flawless. Overall a 5 star since it does exactly what the sales data says it will do... BUT, nothing more... YOU must design your methodology to retrieve the information later. The pen was useless until I studied EverNote tagging and devised a methodology that worked for one user. This was not difficult, but it did take some planning. The flip side is that the LiveScribe/Evernote Combination is very flexible, particularly for Outlook users. The Outlook integration for Evernote compliments the pen flexibility.
