sure have...and ive used countless other Android devices...and yes the Fascinate is very smooth...as is the Incredible, and especially the Thunderbolt using Sense...but i still feel the 4 takes the cake...the TBolt might be just as smooth overall though...i have a friend that just got one, so i need some more time to play with it...
I'm still not sure where you are getting that the iOS UI is "smoother" than Touchwiz, of the TBolt... I've used a Fascinate, an Ally, an iPhone (3 & 4 actually), and a TBolt...
The Fascinate and TBolt have the "smoothest" UI. In fact, it's even smoother than the iPhone 4's UI (Fascinate and iPhone 4 being side-by-side, I've seen it). The iPhone stutters while trying to re-draw the screen at times, takes a pause when opening folders, and in many areas seems to hesitate.
I've not experienced any of that with the Fascinate or TBolt... So, take them side-by-side and use them (Heck, go to the store and do it, they don't seem to mind lol).
haters gonna hate i guess
It's not a "hater gonna hate thing"... I hand off to the iPhone what the iPhone's pro's are: Great display, long battery life, and simplistic UI. But, in all reality, I can't fathom where this argument of "the iPhone is smoother" comes in, unless they are comparing an LG Ally with an iPhone... Or, some other sub-par hardware.
its not an "Apple beats Android" thing AT ALL lol...this is part of the problem...what happened to being able to respect and appreciate other pieces of kit regardless of who makes them, or whether or not you choose to use them?...brand loyalty doesn't really get you anywhere...
And, I'm not even claiming that. Like I said, I give credit where credit it due to Apple: They designed a simplistic, easy to use smart phone. However, I just can't understand the "the iPhone is smoother" argument, when I've seen the device side-by-side with equitable Android devices, and can clearly see the stuttering and hesitation on the iPhone.
