I've managed to hack Honeycomb 3.1 onto the Motorola Xoom I am evaluating. The highlights that are outlined are all implemented, and to summarise;
- its faster
- screen transitions are smoother
- Adobe Flash seems to have less impact on the device
- Stock system widgets are now resizeable - duh!
- Most importantly, the e-mail client now actually deletes mail from IMAP servers
Its an incremental upgrade and should have been called 3.02. But hey, marketing.
