One anomaly to this is the 'classic' MacBook Pro. The basic design is unchanged since 2008, although the internals have been improved on several occasions. The last time it was updated was 2012 yet, remarkably, Apple still sell it. Fan-boys and snobs often tend to denigrate it, yet the reason Apple sell it is precisely because people have wanted to buy it. And the reason they do so is because you can upgrade the components yourself. Take the back off - no special tools needed - and you can swap out the memory, hard drive and battery in a matter of minutes without any great technical skill. Plus it is the last Mac that is supplied with a built-in optical drive - a lot of people still do use CDs and DVDs!
But, finally, it looks as though the traditional MacBook Pro is about to go. Many retailers in the UK are heavily discounting it - almost unheard of for Apple products. For instance, at the time of writing John Lewis have knocked £200 off and are throwing in a 3 year warranty (many other retailers also have it at £699). At a guess, we'd say that production has now ended so it's a case of 'while stocks last'. £699 is still steep for a laptop with 4GB RAM and a 500GB mechanical hard drive, but for another £100 you could upgrade it yourself to 16GB RAM and a Solid State Drive (SSD) and you'd have a machine that really flies and can be expected to last many years.
