Disagree. I'd put that pretty low on the list

1. Securing Wallets by default (watch the chaos when a virus/trjoan hits)

2. Mining pool operator gains 51%, or colludes with other mining pool owners to get > 50%. Needs to be a switch to the distributed style mining pool, where the owner does not have the same amount of control (cuddlefish idea, but enhanced a bit)

3. Network defense of govt takedown/attack - allow for flexible port-switching, tor-by-default, etc

4. Headless clients with geographically diverse supernodes like fallback list (to allow for true mobile apps)

etc...somewhere down there is the .02BTC issue. It's pretty simple, if 1BTC is $20, people will have no problem spending 2-3decimals out. In fact the client should be enhanced to prevent decimal entry errors, by giving a readback/confirmation screen with guidelines.

Try to meet some of these "people" you refer to--regular people don't think like that.  And yes, I can say that because I'm probably a bigger geek than you are--I just work in usability and education.  No hard feelings .  The lightbulb moment for me was when I sent out wedding invitations to people who mostly own bitcoins because of me, and didn't get .01 donated despite getting plenty of cash in cards.  By contrast, I received over 30 tips from random internet users in the first couple months of this year which have now dried up despite the increased community size and traffic (some pieces I've written have received >15,000 views).  People haven't continued being just as free with smaller portions of money--they've stopped spending them altogether. People don't spend $20 objects freely when they expect them to be worth $40 tomorrow, and they don't just move the decimal place over mentally.  This isn't my opinion--I have a pretty large sample space on this one that makes it an empirical observation about the BitCoin economy.
