Devs will find a way. Focus will shift from the meteoric rise to BTC's application anyway at a certain moment. Remember, it is still beta.
I will start to spend BTC when the Chinese electronics sellers start to accept them.
tbh: 5 weeks ago I messaged one of these guys on ebay to negotiate a better price for 4 arduino nano clones by going around ebay (I know, against ebay policy). He made a good price and I paypaled the money. No product arrived and no communication. I must say I'm glad he didn't take bitcoins. Now I can do a chargeback on paypal (hopefully they wont notice I violated eBay policy)... not possible with BTC.
Those guys sending stuff from HK or wherever are great: competitive prices and often good products. However, I don't think I would send BTC to them unless I had previously made good business with one of them.
