“Memory is a critical factor in app performance and the latest Macs have at least 4GB of RAM, and the new iMacs start with 8GB,” Jeff Mincey reports for BohemianBoomer.

“But what if your Mac isn’t easily upgradable to more RAM? And doesn’t more RAM suck up more battery juice on the MacBook? As to the former, there’s Appriority [US$2.99 via Apple's Mac App Store], a Mac utility app which suspends and resumes apps as you switch back and forth,” Mincey reports. “That cuts down on CPU usage and improves battery life.”

If you have a Mac mini, 13-inch MacBook or 13-inch MacBook Pro, OWC is offering memory upgrades of up to 16 GB. Officially these computers could only support up to 8 GB of memory, but using new memory modules it’s possible to increase from that limit, provided users are running OS X 10.7.5 or later… Pricing is at $99 for the 16 GB kit or $51.99 for the 8GB module.”
