With all due respect, probably would have served you better to do more research into what the system was capable of in regards to current software offerings on it before you plunked down $3000 for it. Worse comes to worse, I suppose you've got a very capable Linux box, albeit likely the most expensive one on the market for what power it packs. I'e got a $200 HP laptop (HP Stream) that I run Linux on and it'll run circles around even the most beefy OS4/Linux PPC machines.
I love my OS4 machine, but if I'd bought it believing that it would be capable of doing everything my various windows boxes can do, I'm afraid I'd have to eventually accept the idea that I should have researched the software offerings a bit better before shelling out the cash on it I love it for what it is, but anyone able to use an OS4 machine as a daily driver PC has far more simple requirements of a modern computer than I and most people do.
