so, how easy will merchant adoption be for cryptonote vs bitcoin?
The main issue I see right now is getting people to think about it as something different to Bitcoin, the payment ID thing is a minor usability issue that can be overcome, in terms of integrated payment points that should be no harder than exchanges systems for trading XMR.
The advantages of using XMR for payments far outweighs the negatives of being slightly harder to use. I disagree with the poster who suggested it as a good store of value and not as a usable currency. I personally think it is very much the opposite of that and due to the privacy features is a much more desirable currency to use for everyday transactions than any other options.
