Re: The pace of change
That pace is slowing down, and its type is evolving.
Back in the days of the first IBM PC, it took less than a year to get a more powerful processor. Intel was running full tilt on new CPU designs, and the frequency was always climbing. Every year the new model was visibly much more powerful than the last.
Then we hit the 4Ghz barrier, and there was no more easy way to wring more power out of a CPU core. So, Intel went lateral and started thowing more cores into the die. On top of that, hard disks got their own channel, instead of IDE sharing with another.
Then we got PCI express and SATA connections, making disc access a breeze.
And here we are now, with machines that are multitasking every part of their functions and control being delegated to in the most efficient way we can think of. The consequence ? This year's model is barely faster than last year's.
I used to upgrade my PC's components every year. I haven't touch my main PC in six years now. It still works fine for what I do.
That said, now I am oogling the latest CPUs and graphics cards, and sketching out my dream configuration. Hey, it's been six years, right ? ;)
