Like Goldilox and the three Bears, the major trick to buying technology is buying during the “stable middle” period of the technology. This will give you the most stability and longevity with the technology, after prices have settled down.When technology products first come out – let’s say a major revision of a product, or a brand new computer chip, or a new technology of some kind – it’s called the “bleeding edge” for a reason.So how do you know when the “stable middle” period is? This isn’t as straightforward. You need to so some Googling. You need to find out when the last major revision of the product occurred, and you need to know about how long the update cycle is.Operating system is possibly an 8th point to consider for reducing cost. Don’t pay extra for Windows Vista Ultimate if you aren’t going to need the features, and don’t skimp down to Vista Basic and then wonder why you don’t have the cool Aero interface. Again, compare before you buy.
