My wife is starting a new business as a hair stylist, and she is looking at the galaxy tab and the ipad. THE number one need for her is dynamic calendar management. She needs to be able to easily schedule client appointments, sort by what type (cut, color, blowdry) and quickly send emails or calendar invites about the upcoming appointments to the client. She would also like to be able to attach photos and other files to the client's contact info. Which of these tabs will be best for this? or is there another one she should look out for? she's concerned about the galaxy being too small for these tasks, as well. Thanks in advance.
