I have had a MS for about 3 years now and have loved it; however, decided to take order of the M3. My main reasons was my MS was out of warranty, smaller battery, and only had AP1. From everything I could see online, it received favorable reviews. However, now that I have it, I really wish I just kept the MS. Granted, I have only had the M3 for a day, the MS just seems so much nicer. Any others coming from the MS to the M3 go through similiar feelings?
