The next "big" thing?

I think the next big "thing" is going to be coming with this whole web 2.0 movement. A few months back, Google was hiring engineers to pack as much storage, ram and CPUs into large 20X40 shipping crates as was possible. I think what this is gearing up to do is entirely web-based applications. Computers in the future could merely be terminals to access the internet with and all the overhead and processing would be done on the server side. I'm not sure what to think about this just yet, but I suppose if I ever wanted to do any gene sequencing at home, I could log into one of their shipping crates and have at it.
