I certainly understand that there is a group of people out there who have to have the latest equipment out on the market. Just like any new technology, there are those who have to be the first in line for it. Look at Christmas shopping, when everyone lines up for new the new xbox, playstation, or whatever. There is always going to be this demographic.
That said, if you maintain your equipment, it should last much longer and you won't need to buy the new stuff as soon as it's available. When I go shopping for a new golf driver, I always buy the previous year's model as it is usually half the original price and half as expensive as the current year model. Just sayin.
