I'd say a 2005 PowerPC iBook is obsolete. I'd also say a 2009 intel macbook is obsolete but the truth is, add an SSD into that and it's probably still fine under linux so maybe 2009 isn't obsolete for some users just yet (although i think apple no longer support that hardware). 2015 is modern, intel performance just hasn't changed that much since 2015.
