For people on the go, a notebook (obviously) is the best way to go. For people on the go, a 17″ display that gives you a numberpad is not the way to go. I travel with an 11″ display and when I’m punching numbers, I’m left without a numberpad for ease of use.
For Mac users, this dilemma is gone with the help of a new iPhone app called numberkey. Perfect for heavy duty spreadsheet users, this nifty new application for the iPhone and iPod Touch lets you use your mobile device as an ad-hoc numeric keypad for your Mac. Just install Balmuda’s Numberkey connect software onto your Mac, then grab the mobile app from the App Store for $1.99. The two pieces of software communicate via Wi-Fi, adding a familiar 18-key numeric keyboard to your Mac without wires. Not bad, right?
