Line 37:
** Sure now it would be, but 100 years from now they'll be much cheaper, slimmer, and more reliable. Just look the the history of computers. From warehouse filling computers barely more powerful than an abacus in the Forties, to cell phones at least a million times more powerful carried around by everyone today.
*** but at the same time, the humble wheelchair will STILL be more reliable and maintenance free than fricking exoskeletons.
**** True, just like slide rules are "more reliable and maintenance free" than calculators, yet calculators have supplanted slide rules in every situation. Same holds for exoskeletons and wheel chairs. Truth be told, it is only assumed that they currently are less reliable and more maintenance intensive that wheel chairs. They are certainly more complex, but that doesn't imply reduced reliability. Even if true, the trend for every technology is towards reduced costs and greater reliability. After 150 years of advancement that exoskeletons would still be so bulky and unreliable that wheelchairs would be preferred over them seems far fetched.
***** It still doesn't mean they aren't just out of the price range of somoene like Jake - or indeed, that some people don't prefer a manu al wheelchair, much like today.<br />Also, an exoskeleton would still need the ability to to move your legs and lower body - they are intended to be used to compensate for weakness in old people, or augment strength for emergency services and industrial workers (the latter being what the AMP suit is, except just on a larger scale).
** One word: Batteries. Jake doesn't need batteries to run around on his wheelchair. An exoskeleton, a hoverchair or anything else they could have put him in would not be as electrically energy efficient as a wheelchair; he can keep on rolling longer than a Marine can keep running, given the right kind of terrain (i.e. a human-made forward base with flat floors).

== What the hell is up with the arrows? ==
Okay some else here said that Jake taught the momentum of Banshee Flight + Point Blank tactic to kill the [[
* This has been discussed before. Check out the ''"They are extremely hard to kill" How?'' section in this page.
* The Na'vi arrows ''never'' crack the Dragon's windows, and they never penetrate the AMP windows.
* If you notice when Quaritch is shooting at Trudy's VTOL when it escapes, you can see bullet holes in the glass. That means that glass definitely isn't bulletproof. Given a high-enough velocity, those arrows can penetrate the glass on the [[
** [http://james-camerons-avatar.wikia.com/wiki/Wasp According to the wiki], Quatirch was using a ''[[Hand Cannon|railgun]]''.
** Look closely. Quaritch started using his 'railgun revolver' when Trudy's gunship was facing away from Quartich, so the revolver rounds hit the back. The assault rifle rounds penetrated the glass.
