Hi Baba,

Well the only betas I'm aware of are the three sent according to the Poet road map. Maybe others too. The company hasn't updated that yet.

Honestly I don't know all the specifics but for this first batch of samples I believe the alpha samples were designed specifically for each customer. The Beta samples have been tweaked and produced in mass quantities. Production ready. 

Again if I don't quite have this right but my belief is these Beta samples should meet customer expectations if not exceed them.
