I have an older macbook air running 10.5.8 with a 1.6 intel core 2 duo processor and 2 gigs of memory. I have been running leopard for quite a while with no problems. Should I upgrade to Snow Leopard and/or Mountain Lion? I do routine things - email, web surfing, microsoft office.
MacBook Air, Mac OS X (10.5.8)
You may get a benefit upgrading at least to Snow Leopard:

After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.

If you want, continue using Mac OS X 10.5.8, although it's unsupported. However, your best option is to upgrade to Mac OS X Snow Leopard. You can buy it at the Apple Online Store > http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
Then, make a backup of your data and upgrade to Snow Leopard. You need an external optical drive to upgrade to Snow Leopard, or you can use Install Remote Mac OS X if you have another Mac or PC > http://support.apple.com/kb/HT2129
After upgrading to Snow Leopard, open > Software Update, and install Mac OS X 10.6.8. I don't recommend to upgrade to OS X Lion because you will have performance problems. The hardware of your computer is very old
