Wow, you're really quoting me that... I've been on watchOS and iOS betas since you could get betas.
Then why are you complaining that Betaws are buggy? Are you Apple Watch developer? If not then you are a big part of the problem because these are DEVELOPER BETAS so that developers can make sure their apps are compatible with the changes that Apple is making. Not toys for curious nerds.
Someone who just wants to f around with the new software and is clogging up the bandwidth shouldn't be complaining about the fact that the systems are overloaded.
