THE BEST DEVICE FOR PORTABLE PC GAMING

It's more of a question than a statement, but recently I've been playing more pc games
on my laptop than desktop, and noticed that it was almost IMPOSSIBLY hard to do any
FPS on the trackpad ( I'm getting better tho   ) and that using a mouse while
lying on your bed is rather hard to do too.


So I've been searching around for an alternative, and I've been considering a trackball mouse or some other form of aiming and here's what I've found:

Trackball mouse:
Pros:
A good alternative, can be used anywhere, less wrist movement

Cons:
I heard it isn't as good for aiming as a mouse, BUT, I've seen otherwise:

COD gaming: (PWNING)

Also, if you prefer trackball mice, which is better, a thumb trackball or index finger?

I'm looking into buying the m570: http://tinyurl.com/d8y2jj3


A Trackball Controller:

This is one of my favorites, I've used a wired Xbox 360 controller to play halo on my laptop,
which was alright, but when I tried using it on online cs 1.6 I got a spanking like no other  .
After that, I decided not to consider a Gamepad for PC fps UNTIL I found a trackball embedded into
an Xbox 360 gamepad:

This seems like an awesome alternative, and I could probably compete with Online PC FPS.
Also, It seems like they're trying to showcast a version at the 2013 E3:

LightGun:

Now tell me, who wouldn't like to rush into COD or BF3 and start fragging Duck Hunt style?
It seems like a good idea to be able to point where you want to fire, but the only issue is
that the only design that is a available for pc is stupid expensive (600$):

EyeCam:

This is still a prototype design, but think about how awesome it would be if
you could shoot with your eye? the technology is available and here is the design:

To build one costs 200$, and instead of using it to write you could use it to aim.




There's all the options I have as alternatives to a traditional mouse, I'm currently considering a trackball, but I may just buy a wireless mouse or the Razer Deathadder Infrared Gaming Mouse, it seems nice.


Thanks and tell me what you think   .
