Ignorant? How is that ignorant? Selfish, maybe...
Sure, they can evolve. Anything can evolve. But do we really want it to? I do believe that the software and hardware we have does us pretty good. All this talk of touch-screen's and voice activated commands isn't helping me believe otherwise, because many of us prefer more "archaic" means of input.
Why would I want it to stop? I'm the kind of person who likes to keep her computers for a good 15 or 20 years before upgrading.
I do realize the pro's need more power. But once they get the amount they need, that should be the limit. Who actually needs more then they have?(Of course it's ok if you realized you need a Mac Pro after buying an iMac, thats fine.) If software development focused on utilizing what power people already have, instead of forcing them to upgrade to use the software, the answer would be next to no one.
So your saying that you like to keep your computers for 15 to 20 years, but you haven't really experienced 15 to 20 years, so I'm guessing you don't quite understand how long that it. Lets see 15 years.... 1992. Before Windows '95.... Lets take a prime example of a stunning computer from that era.
The Macintosh Classic II:
9" B&W screen
16 Mhz (actually it was less they just rounded it up!)
2 MB of RAM!!
40 MB HD upgradeable to 80!!
But you are lucky enough to get a modern floppy drive.
I could live with that. But 20 years, that must be pushing it a bit, lets check:
512 by 342 pixel screen. I think my digital watch has more pixels.
8Mhz. It was a screamer
1MB of Ram.
NO HD. So no worrying about losing your files!
Yes, you are positvely right. The refresh cycle is 15 to 20 years.
Please your speed may be nice and dandy for what you do. But computing has hit a bit of a lull recently for minimum specs. A combination of little overall GUI expercience garnered with a rather less than rapid advance in technology (in comparison, in 5 years between 1987 and 1992, Apple came out with a processor DOUBLE the Mhz. DOUBLE!!!!) But things are changing with the introduction of vista the stakes are being raised for hardware you need to run stuff. Wait for the emergence of multi-touch displays, 3D interfaces. Another mini-revolution or another large leap is coming in the evolution of the GUI (we seem to get them every 7-10 years, and last time I checked we are working almost with the same stuff since Windows 2000 or the release of OS X. You see we are just entering the 7 year window. While expose and widgets were all really nice, the general look and feel of OS X is the same. The dock, advanced window control, pretty GUI. It all started around 1998 and really garnered almost complete ubquity in '01-'02 (That is if you call XP pretty....) But either way it obvious things are acoming. We've heard about multi-touch but its only beginning to make its technological debut in phones, tablets and etc. Expect it to become a lot more mainstream next year when one will be able to relatively easily buy a screen with it. 3D interfaces. Multiple desktops. Touch screens. The GUI is getting more complicated and a more simple way to control it will allow us to deal with it (it sort of works that way, someone only develops Expose once you start running more than one program at a time). You have multiple desktops.... you need some way to play with it. And what does all this take.... computing power. Megahertz are nice but multi-threads are nicer for this sort of task where raw power isn't needed but the ability to do multiple tasks simultaneously quickly. Once we start seeing the norm to be two or four cores in computer (within a year or two) then you will start to see software that takes advantage of it. Then you will start to see advances in GUI that will need it. And thus in 3-5 years, your current iBook/Powerbook/Macbook will be just as useful as this lousy Blue and White G3 I can't seem to get online underneath my desk. Its great for playing music off of and typing. Its just sucks to use if I can't use the internet. So while you feel everything is going well (just as people thought at the height of the DOS-era it can't get much better than this, chips are becoming so fast you can't even notice the wait time. Complicated software to make graphs, spreadsheets you name it! Then came 1984 and people wanted to see what they were doing. Then came the 90s and people wanted to see in color. Then came the end of the 90s and everyone wanted to use these colors to actually look at something nice. And right now it all seems so well. But wait a couple years and you wont merely want to see these colors youll want to be able to control at the tips of your finger. You will want to merely reach up to the screen and open you word document. It seems like something you dont really need! And you dont, it only makes your work easier, more efficeint, faster, and more enjoyable. And thats what has happened every 7-10 years since the emergence of the computer. You'd be suprised in my chem lab we have these computers from the 80s that run solely DOS. We have them cause the school never bothered to buy Excel. It was easier to just keep their heavy investment in this graphing software that they paid steeply at the time. It works. I put my numbers in, I click graph. And I print. But I can't go back if I accidentally messed up a point (i have to start from the beginning). Its in B&W. It works... its just so much easier to whip out my laptop, open excel type it in and see a much more aesthetically pleasing graph. And pretty soon I will want to be able to manipulate the graph with my finger tips, and spin it in 3D.
The world evolves. There is no point in saying we no longer need to move forward because we will. We may not need as much power right now, but we need more battery life. And in a couple years when we do need power we will be lucky enough to be able to get it. And I think when you go off to college in 3-4 years you will be begging your parents for a new laptop to go with you. Probably a laptop. One that you can touch. With OS Lemer and Windows 2010. And you will say its too slow for all this touching, and only 4 years later will you feel like finally, I have a decent computer that is fast enough to handle all my tasks. But wait... there is something around the corner....
