I am looking into buying the m100 for my wife to replace her Franklin planner. However, I don't know if I should get the m100 with 2mb of memory, or the m105 with 8mb of memory. How much information, addresses, notes, to do items, etc. can be loaded before exceeding the 2mb limit? Any ideas or averages available? She has probably 150 addresses and phone numbers, and 5 - 10 "to do's" for each day. I appreciate any advice!
