The Future Of Micro SD Cards?

Yesterday I bought a micro sd for my cellphone, the price is only $20 for 2G storage! How can it be possible? You know, you had to pay at least 20$ for a 1G Micro SD Card a year ago, but now it is quite different.

But think about it carefully, it is quite reasonable, you know, our technologies are developing rapidly every day, so of course their costs is greatly decrease, no wonder we can get a 2G micro SD card with such a low price.

Now I'm thinking one thing, what will the future of micro sd cards be? Will they be profitable like past? And how can producers earn profits from them since they are cheaper and cheaper?
