> _.chain([1,2,3,4,5]).map(function (x) { return x * x }).first(3).value()
[ 1, 4, 9 ] // the same if first(3)
> _.chain([1,2,3,4,5]).map(function (x) { return x * x }).first()

Xiaomi

build:

• feels like iPhone 3G - plastic back, thicker than iPhone4 and above.
• sturdy enough, but I'm worried if its dropped into water. iPhone is better sealed out of the box.
• sits well on one hand without a case. iPhone built for adding a case.
• screen - some weird uneven chemical spots, probably need to use a protector.
• camera produces pretty high quality photos, auto focus could be slow.
• battery, similar to iPhone4, slightly better.
• wifi range, similar to iPhone4, not any better.
