Apple was expected to introduce its Multi-Touch Magic Trackpad when it announced its earnings last week. That didn't happen, but they have introduced it today along with updates to the iMac line. The iMac line has been updated with the latest Intel Core i3, Core i5 and Core i7 processors and new graphics. Apple says the line is the fastest ever with dual-core processor speeds up to 3.6 GHz, quad-core speeds up to 2.93 GHz and "discrete" graphics including the powerful ATI Radeon HD 5750.
