When will the Macs be refreshed

It is a question that is often posed to us: at what moment will Apple renew its product line; is it better to buy now or to wait? It should be said that all has been calm for a long time since the topic of interest in the Apple world has been the 3G iPhone and MobileMe.
However, it is now relatively straight forward to know that the machines will soon be renewed. It is enough to go to see what is in the Intel catalogue. Here thus a small summary by range:
- Mac Pro : Nothing envisaged from the manufacturer before the end the last quarter 2008. It will be certainly updated beginning 2009 and will integrate the Nehalem processors.
- MacBook Pro and iMac Although very different in their form, they are close with identical architectures. Intel has Centrino 2 for them. They can thus be updated at any moment. These changes will not be massive, at least with the frequency of processor, with a possible gain of 200 MHz. Note that they will inaugurate GDR 3.
- MacBook: Intel has delayed the chipsets centrino 2 equipped with integrated video. Thus there is nothing but to wait on this side; hopefully by the 'back-to-school' period but perhaps even into the month of October.
- Mini Mac: The thing is more delicate, it is the decision of Apple not to make them evolve at the rate of innovations of Intel; this being only political and not technique. Thus it is difficult to say when they will be entitled to an update
- MacBook Air It would not be surprising if Apple updates it soon, at least to propose it with SSD of larger capacity and also move towards the SATA interface. It could then gain a little in CPU frequency by adopting engraving in 45nm, which could also bring a gain in battery life.
Of course, we can make forecasts only on the internal structures of the machines. It is obvious that Apple soon will re-examine the design of these products, but nothing says that it will be the case as of this update. The beginning 2009 and the arrival of Nehalem can be a favourable moment for their introduction.
In the meantime, those which cannot wait any more can pass by the Refurb Store, these are always excellent and whose price their will make it possible to resell their machine with a smaller loss if they decide they want to upgrade quickly some time later.
