1 minute blocks totally fail the Starbuvks challenge. Are you going to stand there at the from the of the line waiting for 1 minute before they give you your coffee?
Orhpans are not just an issue for miners. As a seller, with a high orphan rate you can't be sure that even that one confirmation you did wait for is enough. The transaction might disappear if the block is orhpaned! So you will definitely want to wait for more confirms. Often people will accept 1-confirm bitcoin transactions because bitcoin has such a low orhpan rate. If a tranasction is in one block, you can be about 99% sure it will stay in the chain forever. That's not true for coins with too-fast block times any many orphans and reorgs.
The only way the starbucks challenge works is with some different kind of technology beside just a block chain. Green addresses, green multisig, off-chain transactions, etc. Block time has nothing to do with it.
Please keep the 1 minute blocks! Else Monero wont have a chance to compete with other coins for mainstream adoption. It's simply to slow for every day transactions. Any coin that shall be used in daily live has to beat the "Starbucks challenge", that is: Buy your coffee and settle the payment before you walk out the door. No merchant will accept a payment that requires him to wait minutes for settlement when credit cards or cash do that in seconds. If you argue that 1 minute blocks result in too many orphanes and are thus unfavorable for miners, I ask you to rethink your priorities when it's most crucial to design a friendly experience for the users instead of the miners that will stay regardless.
On the issue of emission schedule, Im also in favor of a flatter curve. 87% in 4 years is not much time. Most likely thats when cryptos really catch on. We should think middle- long term instead of short term gains if we want this one to succeed and also provide a reliable Bitcoin-like source of revenue. I'd be happy to halve emission per block while keeping block times intact for the greater good.
