Anandtech published a detailed look into OSX 10.10 and iOS 8.1 and how they interoperate. Online ad network Chitika compares Yosemite post-release adoption to Mavericks and Mountain Lion and finds that free upgrades matter a lot. Cult of Mac says that Yosemite’s new Mail version is a memory hog. The San Jose Mercury News contrasts Apple’s conservatism in gradually changing OSX and iOS with Microsoft’s recent penchant for making overly bold changes then backpedaling.
… I stick with Mac OS X Snow Leopard on my 4GB 2009 era MacBook. I have heard tons of “horror stories” about Mavricks and now Yosemite. *sigh* besides I think my MacBook is too old to gain anything useful from an OS upgrade.

You are running an OS which isn’t even supported by Apple anymore. Getting your system’s vulnerabilities fixed can be quite useful if somebody tries to exploit them.
10.9 and 10.10 will just run fine on your computer. The main performance bottle neck will be your hard disk, if you haven’t already replaced it with a ssd. Your macbook will feel double as fast if it doesn’t have to wait for that slow turning metal disks!
Most of the time the reason people are complaining about a new OS’s “bugginess” it isn’t the OS which is to blame but their old software, often stuff which they haven’t used in ages. That’s the main reason why I fresh install makes sense, you won’t drag old garbage with you which you don’t even remember.
Well ok I blame Apple that their changes in mail.app did break the gpgp plugin again. But maybe they actually didn’t change stuff just for fun.
I wouldn’t want to go back to 10.6. The only thing I miss is Rosetta for old mac games.
PS: I’m running Yosemite on a MB from 2010 with 4gb, specs should be very similar to yours
