Why iPad Air 2 is skinny

It's safe to say that you don't buy most Apple devices
these days with the expectation that you can open
them up , and it looks like the iPad Air 2 is no
exception. Do-it-yourself repair shop iFixit has torn
down the new tablet and found that it's even tougher
(or at least, more expensive) to fix than its
predecessor in a few respects. That bonded display
may be great for cutting back on reflections, but it
increases the risk of breaking the panel when you're
prying things open -- and it'll cost more to replace if
you do break it, since you can't separate the glass
from the LCD. Problems from last year persist, too,
such as the use of glue to hold seemingly everything
together instead of clips or screws. Another change
from its predecessor is the battery -- the 27.62 Wh unit
is smaller than the original Air's 32.9 Wh capacity,
although a more efficient design should keep battery
life close between the two. Is any of this a deal
breaker if you're set on getting an extra-slim iPad?
Probably not, but it's something to consider if you
normally prefer to fix gadgets at home instead of
taking them back to the store.
