Update it and disable the logging features. It's written that makes it MUCH faster and responsive.
It's definitely not slow. I spent 30 minutes and turned off all the logging and upped the cpu to 1.5ghz.
I'm now playing Angry Birds HD with a few browser windows open, a few apps (epicurious, email, chat, photo/videos, maps) open AND youtube webpage open playing a video at the same time. The impressive thing is that I can even quickly switch between the apps without any lag. This is just a test, but it's nice to know how smooth it can be.
