Agreed, but Apple also doesn't upgrade the Mac mini
Nonsense……
My first Mac Mini came with a 1.25 GHz processor, 256 MB RAM (upgraded to 512 to run a USB mobile broadband connection), two USB 2 ports, Firewire 400, an Audio out jack, DVI video out, 10-100 Base-T ethernet and Panther (upgraded to Tiger).
My second (and current) came with a 2 GHz processor, 1 GB RAM (upgraded to 5 GB to run Mountain Lion, which requires a minimum of 2 GB) Five USB 2 ports, Firewire 800, Audio
out and in jacks Airport, Gigabit ethernet, Bluetooth and Leopard (originally, and can run El Capitan)
The latest line-up may have dropped the quad core option of the 2012 range, and the base model processor is rated at an efficient 1.4 GHz, but it can boost up to 2.7 GHz for a bit should the need arise. It comes with 4 GB RAM which, though no geek's dream, is adequate for basic use, and is likely to be so for some time to come. They do, however, come with better connectivity than the previous model.
Models with faster processors and and 8 GB RAM can be had off the shelf, and higher specs can be custom ordered.
Except for the dropped quad core model, all perform at least a little better than the previous equivalent.
Upgrades may not always be spectacular between generations now, but they are there. As personal computers approach their fourth decade of existence, upgrades across the market have started to become incremental rather than revolutionary.
According to the mac rumors buying guide, mac minis were announced on Aug 2007, Mar 2009, Oct 2009, Jun 2010, Jul 2011, Oct 2012 and Oct 2014.
None were announced between October and March.
What about 2005 and 2006, and unannounced upgrades? Even the latest model had a minor upgrade in custom options available around February 2015, that was not announced
