I had problem connecting to my corporate exchange email with Honeycomb. Honeycomb did not have the necessary security features to support my company's security policies. After upgrading to ICS, I found that I am able to setup my corporate exchange email but I have to enable encryption, which takes about 1 hour or more to setup on my tablet and this is irreversible. After encryption, I will have to key in pin to unlock and also to boot up my tablet. If in the future, I want to remove my corporate exchange email I still need to live with the encryption restriction unless I factory reset my tablet. This is a major turn off. I did not have this issue with iPad/iPhone. I can setup my corporate exchange email address on my iphone with ease and I don't have to live with the added security once I remove corporate exchange email.
After some research, I found that Apple's devices after the release of IOS 4 have hardware encryption out of the box. That is why iPhone and iPad are widely support by corporates. Android like IOS support encryption after version 4 but as Apple implement the encryption better than Android with hardware encryption. Maybe that is why my 3GS is rather laggy when I upgraded it to version 4. 3GS might not have the hardware encryption since it was release before IOS 4.
For me, I am rather hesitant to enable encryption. The reasons are;
- Performance issue. Since it is not a hardware encryption, it might affect the performance of my tablet. Motorola says Xoom 2 support data encryption but did not mention if there is hardware encryption on the tablet.
- Battery life. I have researched on the net. Most people say the encryption does not affect performance.
- It is irreversible. If I remove my corporate exchange email, I still have to live with keying in of pins to use my tablet.
- Encryption on Android devices seems to be in the infant stage. There might unforeseen issues with encryption. There are cases whereby the phone which was encrypted reboot in the middle of the night and the user could not receive call and alarm could not work, as the phone need a pin to boot up.
