I just got the Business version, but I am actually waiting that the (slow) download of the Enterprise one from the Microsoft VLM website completes, and I will be testing that, next week, on two or three laptop models. We'll see...

I experienced no crashes with previous beta versions, though, on Thinkpad R50e, R52 laptops, fortunately. I did experience some random crashes on older R40s, though. I was testing one of the first betas, at that time, however.
