Micropayment channels don't offer the flexibility of plain micropayments. Sure I can get $0.0001 from you a certain number of times, but I have to wait until I have a certain amount paid for it to worth it for me to make a transaction. Micropayments that aren't channels will be possible when fees are lower.
