I installed Honeycomb 3.2 via the SD card last night. Everything went smooth and I like the standard Honeycomb interface. There is an app to download a newer (?) version of Dell's interface, but I'm not sure I will do that.
However, it did erase all of my downloaded applications. It installed many new applications, some of which were the same as what were already installed when the Streak 7 came out of the box. I had no problem downloading those apps again and they seem to be working fine.
Worth the effort. Now, is there a revised Operator's Manual that describes the changes associated with using 3.2 versus 2.2.2?
