As far as I know, being a semi-professional geek, there's no difference in the CPU or GPU in terms of raw power between the backwards compatible ones and the PS3 slim. The only hassle I'd see would be the communications issue and possibly a bit of lag depending on whether you're wired or wireless.
For My $.02, I'd say get a Bluetooth keyboard and mouse. You can pair both with the PS3 and they work swimmingly. That way, you can choose controller or mouse/keyboard depending on whichever works better for you.
The advantage of a gaming console is purely that the developers have a set hardware environment to work with, and they don't have to keep adapting their programs to all the different stuff on PCs. So you can tune a program to run tighter on the PS3 or Xbox 360 than you can on a PC. The DOWNSIDE of the consoles is you have a set hardware environment to work with while PCs are much, much easier to upgrade. So when you have a seven year old console, it may have blown computers away five years ago... But now you're having to build a "dumbed down" version for the console that doesn't have all the shiny of the PC version.
