Yes, more than decent.
If mine fell down a sewer I would replace it without a 2nd thought. To me it's the perfect size. Right between the X and Incredible. Any larger and I wouldn't be able to one hand it for dialing/texting. As was said above it's about top drawer hardware for what is available now.
It's plasticky and slick feeling compared to the Inc but I actually prefer the feel with a case on it. So the thinness is plus. Doesn't feel like I'm putting some brick in my pocket with a case on it. Glass is Gorilla Glass so its about as tough as you can get. But I think most people run a screen protector anyway. (I do)
So what don't I like. I don't like the power button on the side and don't like the headphone jack on the top. I'd rather power switch on top and headphone jack on bottom. Of course everyone has their own preferences for those type of things.
Some things I didn't like were fixed with the last OTA update. The GPS was fixed and the softkey backlight stays on as long as the screen timeout now. Now the GPS typically shows what side of the road I'm on when I'm walking/running with it.
Screen is hella vibrant. There are people who say that the SLED screen on the Inc is better for text than the SamoLED screen on the Fascinate, and there are pictures on the web showing a very slight halo on text on the Fasc screen, but I've yet to see one person complain about it in actual use. When I zoomed way in on text on a web page on the Fasc and the Inc side by side I couldn't tell a difference.
Battery life is somewhere in the middle of the pack for android phones. Same with reception and call quality (based on the few people i talk to about phones)
My buddy has an X (and likes it a lot). He watches lots of movies while on long flights so he likes the bigger size. Plus he has monster big hands so the X probably feels to him like the Fasc feels to me. The X has an HDMI port that the Inc an Fasc don't have. (non issue for me).
All the people I have met with new phones are showing up with Fasincates or Iphones. (Why someone wouldn't wait for the Iphone 5 at this point baffles me).
One Fascinate owner switched to Iphone when his Fascinate got smashed, but he has no idea why he wanted an Iphone. It just seemed like the thing to get because of all the publicity I guess.
I've yet to meet anyone who chose a Continuum. Smalls size might be nice for people (females?) with small hands.
When I got my phone I rooted manually using ADB, debloated by freezing apps with TiBackup, and shoehorned in the browser from the Canadian Galaxy S Mesmerize that defaults to Google instead of Bing.
When 2.2 was leaked I ran the all in one package (Root, CWM, and 2.2) that is available. From start to finish (phone restored to pre 2.2 flash) was about 15 minutes. This included reinstalling the swype beta keyboard and flashing a debinged browser. Can't get much easier than that. Of course you can do it with individual packages as well.
Anyway that's my take on it.
