I wanted to know what you guys think about this topic and when it would be reasonable to upgrade iPads, iPhones, and MacBooks.
I'm not talking about getting the latest in a year or two
Because its the latest but a reasonable time to upgrade it given that one has purchased an apple product for an efficiently built, strong built reliable device.
Thanks !
The rule of thumb I use is the following:
When the Apple device is either:
(a) Unable to run the latest OS (iOS devices) or one OS behind the current OS (Macs)
(b) Unable to run a given app, program, or task at a peformance level that is to your liking (while within reason).
(c) Broken and the cost of repair exceeds the worth (in terms of time, energy, and usefulness) of a new one or like model to the point of not getting your money's worth to do the repair (Hint: Apple Store Employees are really good about telling you when it's not worth to spend money on a repair or [in the case of the iOS devices] out of warranty replacement)
...That's when I upgrade/replace.
This tends to be:
~3 years for iPod touches and iPhones
~2.5 years for iPads
~3-4 years for Mac minis, MacBooks (when they existed) MacBook Airs and 13" MacBook Pros (both retina and non-retina)
~4-5 years for whichever size of iMac is the lower of the two at the given time as well as lower-end 15" MacBook Pros
~5-6 years for whichever size of iMac is the larger of the two at the given time as well as higher-end 15" MacBook Pros, and all 17" MacBook Pros
~6-8 years for Mac Pros
Though this only applies to my points (a) and (c) as point (b) is entirely subjective.
