You are missing the point. Most people wanting to run AROS on PC will tend to have newer, not older equipment.
Well good for them. Meanwhile, I'm stuck choosing between getting a big-ass 15" Powerbook that I
know will work for non-OSX purposes because it has a Radeon chipset, and getting a more manageable 12" one that I
think will work, but it has a GeForce 5200 and I'm hearing mixed things about nouveau's support for that GPU. Old hardware doesn't just vanish into the aether, and some of us would actually like to make use of it.
