How minor of drops? If you have a skin, as long as it covers the corners (that's important!) you will protect against scratches. depending on the drop, you may still get damage. the last couple of years i've used glass screen protectors. i've had to change them a couple of times during the year of owning the phone because of drops that caused cracks (but the screen itself was fine!)
for several years prior to last year i just used a skin and the worst thing that happed to my phone was the corner skin got messed up... the phone itself was fine!
if you are rougher on your phone you are going to want a thin case... unfortunately (or fortunately) there are a LOT of choices for thin cases...
as far as skins, bestskinsever (best skins ever) .com was a good company to deal with. stay away from slick wraps! they have a ton of sales, but then they claim they get busy and you may get the skin in a few months...
i've used phantonskinz in the past, too. great company but i switched from them strictly based on their corners (they may have changed... i haven't looked yet this year!
Thanks for the info! I don't think a skin will do it for me sadly, as I do expect that drops from 1m/3ft on various surfaces will be unavoidable.. if you have info on thin cases that wrap nicely to a matching screen protector, I'm all ears! (or eyes, as it were).
