Reading, writing and daydreaming in a coffee shop is my idea of a good time, what with its background hum and beehive of energy. Sometimes, though, you can't get to a shop, especially in the middle of a work day. That's when I turn to Coffitivity.com. Plug in your headphones and tune into the ambient sounds of a cafe in mid-stride. Choose from Morning Murmur, Lunchtime Lounge or University Undertones. If you're feeling rich, spend some extra pennies and upgrade to Paris Paradise, Brazil Bistro or Texas Teahouse.
