If you have a mid-2010 iMac, Apple has just released the iMac Hard Drive Firmware Update 1.0 to resolve a problem that might prevent your iMac from booting properly. Although there’s no way to know if you really need this update or not, the inability to boot could make installing this update in the future significantly more difficult, so I’d recommend doing it now, after making sure you have a current backup.

Enabling Auto Spelling Correction in Snow Leopard
In Snow Leopard, the automatic spelling correction in applications is not usually activated by default. To turn it on, make sure the cursor's insertion point is somewhere where text can be entered, and either choose Edit > Spelling and Grammar > Correct Spelling Automatically or, if the Edit menu's submenu doesn't have what you need, Control-click where you're typing and choose Spelling and Grammar > Correct Spelling Automatically from the contextual menu that appears. The latter approach is particularly likely to be necessary in Safari and other WebKit-based applications, like Mailplane.
