That is why right now the Bitcoin community should start adopting mBTC or milli-bitcoin. 1 mBTC is $10.10 today. One satoshi is still less than one US cent so I think everyone can still own bitcoins, just in the lower decimals.
I'd go for mBTC. Satoshi is having very low value now and I don't want it to become the unit in which the prices are denominated. But we need to create a name for mBTC, just like we have Satoshi. And we need to create a unique, short name. There have been proposals to rename mBTC as BitCent and BitPenny, but I don't like those names. Let's have something unique.
