Yes, the new hardware revolution is coming, save your money.
...and wait at least three years...let's hold off on that decision a bit... SSD prices are dropping fast and the performance is quite nice.
Q4 should be interesting for the SSD market.
The memristors are a fantastic development and promise to bring some incredible breakthroughs in the near future.
I think it will start replacing flash memory in 3-5 years, if everything proves acceptable then to replace RAM and storage in another +3 years, the processor maybe another few years after that.
Or, it could take off like a rocket and in 3 years we're all walking around with 10x the power of todays desktop computers in half the size of our current cell phone.
Gotta like the possibilities of new Tech.
