I installed it last night. The landscape feature is pretty cool, but having a Nokia Communicator (9500), this is not terribly necessary. I must say that it is pretty RAM hungry, because for the first time since two years, my Commie was out of RAM! Despite of this, it is a very recommendable install.
For me it is the go to browser on my phone, because of its quick rendering, good handle of different web site configuration, and saves on my data bill.
