So now that Apple is offering the Magic Trackpad for free with the new iMacs, that changes my desk configurations with wires and ports. Has anyone opted for the Wireless keyboard and regretted it? Anyone sorely miss the number pad and other generally useful buttons like "page up," "delete" key, etc? A truly wireless and clutter free desktop is very appealing, but I worry I will miss the full keyboard. Trying to gauge what getting accustomed to the tinier wireless keyboard is like. Appreciate any input.
