Cerebus:
You'll find that SMD part elasticity, and hence how far they will fly, increases in direct proportion to the cost of the part. I've never lost a single MMBT3904 transistor in SOT-23-3 (a few pence worth, if that) but last week an AD5620 DAC (£5 worth) in exactly the same sized SOT-23-6 package managed to fly 6 feet and take 20 minutes to find.
Ground_Loop:
The hook on the end of a tape measure is intentionally loose. It moves exactly the thickness of the hook to make accurate inside and outside measurements.

Holding down the space bar on an iPhone puts the cursor in mouse mode. No need to back up for corrections.

Interesting, I'd never noticed that before.  However, tapping anywhere in the text control also relocates the cursor immediately, so I'm not sure what it does for me.  Is there some hidden advantage to 'mouse mode'?

Yes that my fingers are too fat to actually tap in the right place on the screen reliably, so it always ends up off by a character or two.

Its the one advantage that resistive touchscreens had, you could use your fingernail to precisely click where you want.

That spacebar thing changed the way i use my iOS devices massivly. I always hated typing on those, because i make really frequent small typoes most of the time.
If i notice immediatly, i just back up, but later corrections where massively annoying. While you can tap to move the cursor, especially on my iPhone 6s i only ever manage to move the cursor to the beginning or end of a word.
Holding space then allows me to move just to that stupid letter i accidentally inserted :)

I still do not like typing on the touchscreen, but at least it's bearable now for me.
