Thanks mate. I am having diifficulty to understand your first two paragraph.
Anyway, I am buying it now!
Reading it back, it doesn't make much sense to me either.
OK specifically, once the 2014 Mac Mini was released, the base model in the UK dropped from £499 to £399. Refurbished 2012 models on sale prior to launch date were selling for around £429 representing an approximate 15% discount.
AFTER the 2014 Mac Mini launch, the same 2012 Mac Minis were on sale for a refurbished price of £339 - again this was approximately a 15% discount.
At an overnight discount for the same model of £90 that's when I got my base model 2012 and in hindsight I also missed a chance to grab one of the quad core models which were on a couple more times after the launch of the 2014.
The fabled quad core models were still available for a few brief months at the same old price but then the middle tier price hadn't changed. There's not been a 2012 model in the refurbished store for months now so I expect you'll never see one again.
This is just one example that benefitted the consumer there. If you glance at the refurbished iPads you'll see that they are given 15% discount off the re-aligned prices for specs that are largely the same. The discounts can fall between two stools as some capacities were doubled but the prices were increased. If you're considering a refurbished iPad look very closely at the storage capacity of the model compared to what's on sale brand new.
The refurbished store generally discounts 15% off the price tier for the most recent model. They used to put older generations on for even more discount but that's increasingly rare - more supply chain efficiency from Tim Cook?
As mentioned elsewhere, there's also 3rd party retailers including the likes of John Lewis in the UK who may decide to clear out old Mac stock at discounts rather than return them to Apple - Currys/PC World do this too. These never last long, especially if the deal is a good one, so you just need to make a note of the prices and decide for yourself quickly.
Sometimes the discounts are worth thinking about, other times it's not because the newer hardware is significantly different or better. If you're in the market for an iMac have a think about what models are around now, then ask yourself if you'd buy it at some predetermined level of discount.
In this month's case we may well also have a serious price increase to consider thanks to the dire exchange rate. And the worse thing is the newly aligned rate will stay that way till the next update probably in October 2017 even if the exchange rate recovers early next year! I am waiting for UK Mac Pro users to pass out in shock at £2999 for an entry level Mac Pro.
In technological terms, the 2016 iMac may have the following changes:
1. AMD Polaris GPU - these run cooler and are more powerful than the old series
2. If they decide to go thinner with the case, they could resort to using 2.5" hard drives which also run cooler, are quieter, and represent a supply chain win if they can consolidate hard drive part numbers between Mac Mini, iMac and the Time Capsule.
3. Magic Toolbar Keyboard - as rumoured repeatedly for the laptops, why not introduce them for the iMac?
4. Thunderbolt 3 / USB-C - this would be a major change but the 2015 27" iMac had Skylake chips too and could have had Alpine Ridge controller added at the time. I suspect they were waiting for all Mac models to transition at the same time - including the Mac Pro and 15" Macbook Pro which has stubbornly stuck with Haswell CPU and the 13" Macbook Pro which has stuck with Broadwell CPU.
If none of these bother you then perhaps keeping a close eye on 3rd party retailers might be your best bet. And don't hang around if a deal is truly good, and 2016 iMac prices are ruinously high, then buying a 2015 model will make a lot of sense if you can't wait.
