In the market for a new retina MacBook Pro? An iPad mini? An iPod Touch? You might consider checking out a buyer’s guide before you buy, to get a sense of where your particular product is in its release cycle.

For example, I am in the market for a new retina MacBook Pro, as my existing model is a bit long in the tooth. Checking the MacRumors buyer’s guide (click the Macs tab towards the top of the page), I see that the retina MacBook Pro is rumored to see an upgrade this summer.

I can wait that long, and I can see by the notes that if I do wait, I’ll likely get a Force Touch trackpad. Worth it. [EDIT: Turns out the rMBP already has the Force Touch trackpad. Still gonna wait, though.]

There are lots of buyer’s guides out there, each with its own take on the product release cycle and associated rumors. Might be worth checking a few different ones to make sure the rumors all line up.
