Thanks. So I take it PowerPC applications are very old technology?
PowerPC hardware (in different iterations) has been around since 1994. 2005/early 2006 was pretty much the end of sales of new computers based on the PowerPC cpu (Powermac G5's, iMac G5's, etc.) 2006 is when Apple switched from PPC cpu's...to Intel cpu's.
As the link above mentions...with OS 10.6 (Snow Leopard released in 2009) you could still run PPC applications via emulation with the application "Rosetta". So if someone owns a Macintosh computer capable of running OS 10.6 (and thus also Rosetta)...then in 2012 you can still run PPC applications).
Newer Macintosh computers can only run Lion (10.7) and above...so no Snow Leopard...and thus no Rosetta.
One alternative for someone who still needs or wants to run PPC applications...is to purchase an older "G5" based Macintosh running OS 10.5. Powermac G5's can be purchased for around $125-$150 bucks (sometimes a lot less). BAMM...now you have PPC compatibility!
So are "PowerPC Applications old technology"...maybe. Depends who you ask. In the fast paced & quickly out-dated world of computers...yes...PPC applications are old technology. But this doesn't mean that they don't still have some life left in them if run on the correct computer & OS version!
