If Apple had released an iPhone 5 with a 4"+ screen and 4G LTE you would notbe seeing me on this forum. I think the iPhone is the most complete package of functionality, reliability, excellent customer support and build quality of all the phones I've seen. That being said, even though I waited for God knows how long for Apple to implement "cut and paste" on the iPhone, my waiting days were over. I've read about and played in store with just about all the high end phones out there today (and weill know that tomorrow literally will bring the next greatest phone), and decided the Skyrocket is a keeper. I think it's a very nice looking phone (even stacked up to the iPhone 4S and the Razr), and now after having it since launch day on Nov 6th I find it a very solid and capable device.
My biggest concern, battery life, is fading away as I go from fiddling with the phone constantly to a more natural day to day use pattern of calls, checking email, streaming music, listening to podcasts etc. I'm getting almost a full days use out of a charge, and if I come up short I have a spare battery. By the way, as many here have noted, there is a serious problem with the battery level display. It will say100% all day long right up till the phone shuts down. The only way to get a true read on the battery level is to turn it off and on and you'll see the level instantly change.
App availabilty is good. I've found most of my favorite apps in the market (Evernote, Pandora, Kindle, FlightTrack, RadarScope, SiriusXM, Netflix and Hulu+). My favorite iPhone/iPad word game is Wurdle, which unfortunately is not available for Android. my iOS/Mac password wallet, 1Password, has a free reader app for android and is apparently working on a full blown app for the OS. my biggest disappointment is that I'm giving up Omni Focus on my phone, since it looks like there are no plans to build an Android version.
I can't speak to music. I'm not a big music listener and have not invested much time in trying to figure out how to get my iTunes music on the Android. I still have the iPad ans my old 3Gs, so that's not a big deal
I really like the camera in the skyrocket compared to my old 3GS. can't compare to the new 4s since I have not been able to use one out of the store.
I get great download speeds even on HSPA+ (not sure when they are going to throw the LTE switch here in Orlando. Generally I get 3-5 M download, with occasional spikes at almost 10 M.
I love the big bright display. The colors are very vibrant, although I have noticed the somewhat bluish tinge many have talked about. The screen resolution is fine for me, even though phones like the 4S, Razr, Vivid and Nexus have higher resolutions.
Gingerbread is fairly straightforward as far as I can tell. I'd still give ios 5 my vote as a "better", and more stable OS, but that's me. I've read a lot about ICS, and I'll be interested to see how it's implemented on the Skyrocket. It's funny the small things that mean a lot. I was really disappointed when the Bionic that I test delve before the Skyocket did not have built in screen capture (the Razr does not seem to have it either). I assume that the Skyrocket has an iPhone like screen capture (push the home button and then the power button) as part of the Touchwiz interface. I use screen grabs a lot, and am really happy the Skyrocket has it).
Anyway, that's my impressions after a few weeks with the Skyrocket. I'm pretty happy with it.
