Intriguing you would find it slower, I guess it is possible that the binaries are built to the baseline Mac architecture requiring some instructions to be emulated via invalid instruction exception on lower instr sets, which may also explain some of your other stability issues.
But looking at your other comments I'm surmising your main contention is that one might just as well get a real Mac (eg Mini). I agree fully with this, imho the price difference is hardly worth the time to deal with all the various issues around install, upgrading etc.
I've also found the Mac mini to be completely adequate; and it still seems to me that even buying an iMac at $1k+ is still a pittance for a toolchain for this type of platform, considering one also gets a general-purpose computer to boot.
