Received my rugged case today. Very high quality case but if you are "bulk" sensitive you'll need to look elsewhere as this is a beefy rig. Having already cracked my Captivate screen I needed something to protect my phone from further damage and this will surely do that so bulk means nothing to me. The only issue I have with the case is the little plug that covers the camera lens is really hard to get out. I took a pocket knife and ever so slightly trimmed some of the silicone around the plug to make it easier to get out and now everything is fine.
Thee holster is very solid. Felt lined looks like a nice feature as long as it doesn't collect debris and turn it into sandpaper. I'm not sure if this is a concern as I've never used a holster that had felt on it. I guess time will tell on that score.
Best feature over all my previous otterboxes is the two cases in one system. Being able to tear off the spine and silicone and still be left with a slim protective case is a big winner. I need the bulk and protection while at work but not at Thanksgiving dinner so to speak. It takes about two seconds to strip off the bulk and be left with a pocketable protective case.
Sorry for the longish post. Just thought I'd give some initial impressions. I'll try and snap some pics in the next couple of days if you guys want.
