Yes, a 32 bit version of Windows 8 is available. I would only get it if you NEED a 32 bit copy though. Valid reasons for needing it include: CPU doesn't support 64 bit instructions (which like you said is pretty rare these days), or you have a Mission critical application doesn't work properly under a 64 bit OS (getting rarer in occurrence by the day). Otherwise go 64.
I really hope this is the last mainstream version of Windows that Microsoft makes which includes a 32 bit version. It really is time to move on.
I agree; if Microsoft was not realeasing a 32-bit version of Windows 8, it would really start encouraging software/game manufacturers to start developing more 64-bit software. If Windows 8 was only 64-bit, then maybe by their next OS they could've dropped support for 32-bit apps as well. Thanx
