So when I purchased my m15x, I was intrigued by the idea of an express card remote control for my computer. I saw it available on the order page, but decided against it. I called AW, but they didn't know what brand it was. It took me the longest time to figure out what the express card remote was, but I finally figured it out.

Interlink Electronics VP6600 ExpressCard Media Remote for Bluetooth

While searching, I found something else...

MoGo Media Mouse X54 for ExpressCard/54 Laptops
http://www.amazon.com/Media-Mouse-Ex...9362959&sr=1-4

Comparison:

Interlink -
Bluetooth
Stores and charges in 54mm express card slot
Extends about 1/4 inch from the case while in the express card slot
It contains the following buttons:
Volume up
Volume down
Volume mute
Next
Previous
Play/Pause
Stop
Scan Forward
Scan Backwards
Back
Page up
Page down
Up arrow
Down arrow
Left arrow
Right arrow
OK (enter)

Mogo -
Bluetooth
Stores and charges in 54mm express card slot
Roughly twice the cost of the Interlink remote
Acts as a laser mouse
Lighter than the Interlink remote
Fits nearly flush with the case while in the express card slot
It contains the following buttons:
Volume up
Volume down
Volume mute
Next
Previous
Play/Pause
(Thus, it lacks DVD controls)

I like the mogo much better, but of course you get what you pay for. It's a slightly worse remote as it lacks buttons and there isn't a physical separation between the play/pause button, volume up/down, and mute, so you can't really use it without looking at it. However, it can also be a mouse and it doesn't stick out an absurd amount from the m15x case, thus is easier to travel around with.

One word of advice... the express card and multi-card slot in the m15x are directly above the Nvidia graphics card (of any flavor). If you're gaming, take out any express card or memory card in those slots if you'd like to use them again. Of course, when you're using integrated graphics, that portion of the laptop is basically heat-free.
