Microsoft Store once again offers the 4.1-lb. Dell Inspiron 15z Intel Ivy Bridge Core i5 1.8GHz 15.6" LED-Backlit Touchscreen Ultrabook for $499 with free shipping. That's tied with our expired mention from last week as the lowest total price we've seen for any Inspiron 15z touchscreen laptop. (For further comparison, it's also a current price low by $300.)
