I agree that the Samsung Captivate was a big disappointment for me, but to call the Galaxy S as a whole a fail...I cannot agree with that.
The fact that they sold so many itself shows the device to be a success, at the time that is...
As of this minute, the Galaxy S is starting to lean towards Epic (4G) failure. (Pun intended

).
They JUST now announced via AT&T's twitter and Facebook pages that the Captivate is getting Froyo tomorrow, 2/24. The Epic 4G just now got it this week as well, what happened to the whole "By October", or "By the end of 2010"?
I waited, and waited, and WAITED for 2.2 to come out for my old Captivate. Hoping it would fix the lag, fix the random shutdowns, fix the capacitive buttons malfunctioning. But, it became too long of a wait....6 months later, I made the switch to a high-end HTC device.
I will NEVER look back at Samsung again, their mobile market is finished in my book. The only thing I'd consider them for again is an HDTV.
The HTC Inspire 4G is everything I wanted in my Captivate, a working a beautiful UI, snappy, quick, and responsive to the touch (no lag).
The pinch-to-zoom speed is quite impressive, nearly IOS/Windows Phone 7 buttery smooth.
The HSPA+ speed is a good thing as well, I was sitting in my car late a couple nights ago outside my local Gamestop wait to go get my copy of Killzone 3. I got bored and decided to pop up some HD videos on youtube, man did those things buffer fast. I'm talking about 8-15 minute long videos too.
I absolutely love, love, LOVE my new Inspire and will never look anywhere else for smartphones but at HTC.
Just my two cents...
