There are some downsides of course. While Transgaming insists their software wrapper offers little to no slow-down, the reality is that there's still some translation happening. But if you can't notice it, no big deal right? Well, if you're running a PowerPC Mac, you won't be able to notice it at all since you won't be able to run these games. Part of Cider's magic comes from the software's Intel Mac requirement, so if you're running a machine more than a couple years old, you won't be eligible. But that's par for the course for PC gaming and just another way Mac gaming is growing up.
