Got mine today... the lock button
does suck to use, but honestly I don't use it THAT often....
Apart from that (which appears fixable with the exacto knife) the case seems just fine to me... I
like the fact it's a very snug fit. I see no reason to be taking it on/off all the time...it's there to protect the phone, which it can't do off.
The volume buttons don't offer much in the way of feedback but I have no trouble pressing them, and 99% of the time I either leave it on the same setting or I mute it entirely, and the clearance to use the mute button is just fine.
As to the feel... I didn't feel the "old" case so I can't really compare... it is a touch less grippy than the 99-cents-including-shipping-from-hong-kong ebay silicone case it replaces, but at no point have I felt like it's going to go flying out of my hands either... and I happily used a polycarbonate case on my 3G so this is "softer" than that anyway
On the plus side is feels like it offers a lot more impact protection than that cheap/thin silicone case did, and the snug fit is a huge plus in that sense compared to the hong kong silicone one
Most of the cases available for free sucked worse (no back protection, or no top/bottom protection)... and if this version trades "tougher to use lock button" for the "a little loose on the sides/bottom" issue that was the only complaint I saw on the "old" version, I'm ok with that trade.
(as to the side seams, they're way way way less obvious than on that 99 cent silicone case... but again, don't really care... generally the phone is either in my pocket where I don't see them, in my hand against the side of my face where I don't see them, or in my hands for apps/games where, again, I don't see them because I'm looking at the phone not the case.)
About the only thing that would've made me happier besides an easier lock button is if it had a non-adhesive screen protector like my 3G Griffin Wave did, but
nobody seems to offer a case like that for the iPhone 4 other than the insanely over-large otterbox defender.
Hopefully the exacto knife fixes the button issue... can't do much on the front screen issue I guess
