I hate how they screwed up the layout of the keyboard like moving the Win Key from its normal place, so to fix that I just remap the keyboard from inside of Windows. I changed the tilde to a Win Key and I changed the Ins key to a Ctrl key.

The two little holes on the front of the machine (one on the right and one next to the wireless) are dual array mics. The screen button w/ the picture of the monitor changes sceen resolution and sends to a projector or other monitor.

The 2nd battery doesn't go in the media slot. Instead it attaches to the port replicator adapter. It is called a slice battery. It is 6-celled and doubles your battery time. I noticed that this is the style they have gone with for all of their newer computers - the M7 & the R20's.

About Dual Core CPUs: It doesn't emulate have two processors, that would be Hyperthreading. Dual Core CPUs actually have to CPUs on one die, so it really is two processors, just in one box. Also, dual core does NOT help normal CPU intensive applications. The app has to be specifically written to use two CPUs. That said, since each CPU is doing less (since they can split the workload between the number of single-thread processes being done), you do see a great performance improvement. However, it's missleading I think to say that the 2 CPUs makes your applications run faster.

Here is the info on the port replicator. It plugs into the bottom of the machine in the same place the slice battery does. It is anywhere from $179 to $199 - depending on sales.
