No Trackpad on the PowerBook 150 according to Apple. Apparently a popular weekly paper publication slipped up and incorrectly stated that the new entry-level notebook computer sports one of the touch-sensitive devices found on the 500-series PowerBook models. In fact, the 150 has the same rolling trackball found on most previous 100-series models. [MHA]
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.
