I expect this beta with Visual changes to be highly unstable. I will hop on the beta train once Beta 3 is released.
You don't have to renew Dev account just to test Beta. Plenty of developer profiles float around.
Or else get on Public beta.
I used to run betas all the time. I have several subsequent devices I could use. However, they wouldn't see as much use running beta, and I don't think I want to deal with beta woes and unsupported apps this time. I could change my mind after the WWDC announcement. Speaking of which, I need to renew my Developer account before it expires.
