Normally Wednesday is not a very popular day. It falls right in the middle of the week, and is therefore known as "hump-day", it generally doesn't have very good TV shows to watch, and it should be spelled "Wensday" instead of the screwy actual spelling.
However, on this particular coming Wednesday, also known as tomorrow, Apple is having one of their spiffy media events at which they will unveil some fancy new bit of technological goodness. The current candidates right now are a transfigured iPod Nano, and a wide screen iPod with touch controls a la the iPhone.
Check out the usual suspects for the latest rumors. I'll try to post my thoughts once there is something real to talk about.
