I just got mine yesterday. Exactly what I wanted to keep the dust out. I'm only portable about 5% of the time. The rest, the M1210 is open on my desk, but I have an external keyboard and monitor.
The only downside is that the feel of the touchpad is not as smooth. The plastic grabs at your fingertip. If I was more mobile I might consider cutting out the hole - very carefully.
As for shipping, once you choose your shipping method, assuming you have a choice, your presented with options if there are any. I chose USPS and a fairly inexpensive option. It arrived in 10 days. Pretty good from the U.S. to Canada when not using a courier.
