Fantastic thing about being a member of a public board, disagreements can be posted. The sponsorship was not for the 4.5 Beta, but it was informing you that there the BlackBerry devices will support larger size cards. Your statement that the cards do not reach 20gb, is only partially correct. Which was the reason for my correction.

The basic rule is to each their own, you prefer the external HD, others may not want to carry an extra device or worry about losing data with a hardware failure, but giving an attitude will only make it less likely in the future that people on the boards will help you, or that you will have a pleansant experience here. You can post the hardware/software posts that you like, that is your choice, but i would recommend being more polite in the future.
