It can still be planned obsolescence even if the plan is a good one. ;) Apple has always attempted to strike a balance between longevity and progress, especially on Macs (5-7 year lifespan, usually). iOS is faster-moving, and gets the shaft more often (2-3 years, sometimes less). The latter will hopefully get better as the mobile hardware catches up to desktops; most of the forced upgrades have been due to low RAM or other hardware deficiencies.
