Heh, now I want to benchmark some 20year old pc gear. Given hardware drivers available 3d in particular might be interesting.
Back on topic though, yes, the "OS4 hardware is slow/expensive" conversation is old/tiring, but it happens to be an actual consideration if any thought is given to a merger. While those that do purchase a Sam/A1-X1000 seem happy enough with the quality of the hardware it's a pill that's just too hard for others to swallow, especially when they're already happy with their hardware running a very similar system and much the same software that's much cheaper and either just as fast, or a lot faster.
For the price of an a1-x1000 I could buy an i7 AROS machine, a g5 mos machine+license, some amiga-oid software and/or donations and a new tv.
I simply wouldn't have interest in pursuing the hobby anymore if I was forced into the OS4 price/performance eco system.
