Damn straight, I'm using my 200MHz PowerPC amiga here with 258mb ram, Soundblaster 128, 8mb permedia graphics card, USB 2, fastethernet, zip drive, CDRW, etc
IDE hard drives have been standard on the platform since the release of the amiga 1200 (circa 1992).
OK, not quite competing with the PC atm, but the OS still kicks the ar5e out of windoos.
The last hardware to be produced was the EYETECH manufactured amigaONE running 1GHz G4 PPC on a brand new motherboard. Badly designed, lack of support, the company which produced the motherboards (MAI) vanished and loads of bugs became evident. Oh and at around £700 for the motherboard/CPU combo... bit beyond my price range.
IF you're interested check out amiga.org, amigaworld.net, eab.abime.net for all the latest infighting and vapour news regarding the latest operating system (OS4 - yet to be final-released) and the farcical lack of hardware to run it on. Damn shame really.
The amiga community contains some fine people though, in my experience very supportive and helpful.
