Ahead of Thursday's Apple event, James R. A. Davenport—author of the data and visualization blog ifweassume.com—decided to investigate the data behind Apple's product refreshes. Here, he shares his findings about refresh times and changing prices.

As an Apple computer fan I've been a long time reader of Mac Rumors, a website that reports great Mac news and rumors. One great feature is their Buyer's Guide, which tracks the refresh history data (and rumors) to suggest when products are due for an upgrade.

I've been wondering if (a) Apple products are actually getting cheaper over time, and (b) if Apple is refreshing products faster?

Here's the base cost versus the days since last refresh for a bunch of current Apple products on Mac Rumors:

Some products change in price quite a bit, most don't. The refresh timescales also move around quite a bit.

1. Autumn Is the Season of New Toys

This of course makes sense: computers and tech are big items for Back-To-School sales.

2. MacBook Air Keeps Getting Better!

I've long held that the 13" MacBook Air is by far the best laptop Apple makes, and it's one of the only products that show a continuous decay in price. The Air has steadily transformed from a niche high-end portable to the standard entry-level laptop!

3. Update Times Are Getting Slightly Shorter

This isn't a highly significant result, but it's interesting that release timescales in the last 2-3 years have started to converge to a slightly lower span.

4. Cheaper Products Usually Get Renewed Slower

...except for the Mac Pro, which is the most neglected Apple product usually. This result was very counterintuitive to me, I figured there would be more volatility in the lower-price products and thus shorter refresh timescales. This "trend" is driven by the rapid refresh times of the Air and Retina laptops.
