I think it can be. Or at the very least between the little boards and the USB computers, they'll fill certain market or two.
Most people probably use a computer like you (dink around on the internet, play music, do email, word processing). They don't really need a powerful computer unless they play games on it. Sure, it might take 30 seconds or longer to load something as opposed to 5 or 10, but you're possibly saving yourself hundreds of dollars for sacrificing a little time. Then again, since the SD cards are solid state, you probably wouldn't really be sacrificing much in time.
It does come at a price though. It won't be portable like a laptop or netbook (yet at least, maybe in the future it can be somehow). But the bigger issue is drive space. Similar to a netbook, you probably won't have a large drive (or SD card in this case), since more space can mean a lot of money (although SD cards are getting cheaper). So you will probably need an external drive or another computer to act as a server to store files. Another option might be to utilize online storage (cloud service) such as Google Music/Drive or possibly Amazon.
Time will tell. I have a NAS so local server won't be an issue. And I am waiting for a few Raspberry Pi's to ship that I want to use as a media center for a couple TVs and a replacement for a netbook that I want to use to develop on. For now, it's probably just a novelty, but I can see these things possibly being a lot more.
The irony of the information age is that we can't necessarily trust all the information.
Just think of how stupid the average person is, and then realize half of them are even stupider!
