I think chasing the ultimate machine is a fantasy foisted on us by marketing machines. All they try to do is make us think we can make better products if we just spend a few hundred more on a new package.
Not one package will make us better or more productive. No not the latest on Photoshop or Illy. Not the latest wide format. Not the latest computer. Every thing we need to do well is in our minds.
Save the money. Get out of debt and feel the freedom.
That really depends on the individual circumstance. The latest computer in my situation has improved efficiency. It's able to process commands quicker and now with having the ability to have 3 monitor outputs, I have a far less need of flipping back and forth between programs. My computer before that was less then a year old too, so it's not a question of time. Sure you wait long enough, your old computer will get bogged down as it is, just the natural coarse of things.
This is something that has to be examined on an individual basis, however, this certainly not going to apply to everyone. Not all new improvements are necessary for efficienty, but if you wait long enough there will be one that you'll have to upgrade to. Unfortunately, you might have to upgrade before then as with tech things, computer companies and software companies want to make sure you get the latest and greatest and it's very easy for them to do.
Save the money. Get out of debt and feel the freedom.
That slogan sounds an awful lot like what I hear on the early morning infomercials before I take care of the horses.
I agree for a good bit of the time you are correct, but not in all situations. The latest and greatest really is the latest and greatest. I'm far more efficient with this computer then I ever was with anything on the XP platform, and the vista OS was to much of a power hog just for the OS itself.
I usually do a C/B ratio to see if something should be had or not in order to see if it is really worth it or if it's a matter of want. No one here can tell you if it will make you more efficient or not, because more often then not they will be going off of what would make them more efficient or not.
