I thought I'd just stop by and chime in here, I too came from the iPhone to Android long ago (iPhone 3G 16GB Was the top end at that time). Over the years, there have been some great phones and some stinkers...
My first Android phone had a bad cellular radio and despite living a block away from the tower, I had no service inside while my work phone (a BlackBerry 8310 unlocked but an AT&T model ) had full signal strength.
The first phone? It was a Samsung Behold II, having been with T-Mobile over 14 years now I never had so many problems but it was Samsung's first Android device. Compared to my iPhone, the Samsung camera absolutely crushed it at 5MP with a LED flash. The major problem with that Samsung phone was it's software. Still very early but showed much promise and the first AMOLED display along with the hardware made it beautiful to look at, but a pain to use.
No Mac support either.
The first truly great Android phones came out with the Mytouch 3G series and the Motorola Cliq (hardware qwerty device). I ended up buying the limited edition Fender edition which was a great phone despite a few issues. The price was as high as the most expensive phone in retail at T-Mobile $449.99 MSRP which was also unable to be returned due to it's limited edition nature.
It had a painted wooden sunburst finish along with the rest of the accessories even down to the included stereo earbuds. It was truly unique and the first phone I could compare to my iPhone 3G. Both bad 16GB of storage, the same display resolution, and some similar applications.
The Mytouch line back then was a HTC only affair and the Fender phone had a great build quality but nothing like the HTC models of now which are very unique.
I loved being able to customize nearly anything at that time as the MT3G was a stock Google phone. No HTC sense, just stock Android 1.6 "Donut". It was a step back in the technical area compared to the Samsung with a 3.2MP autofocus camera but without a LED flash, and due to some relaxed hardware, better battery life.
Fast forward to today, Android really has made amazing advances and pushing the smartphone into near tablet with larger screens, cameras that can keep up with nearly any point &shoot, and processors that would have never been thought possible on a mobile phone.
While I don't have the One X, I do think it's a great phone. I closed down my account with AT&T but stuck with T-Mobile and currently still use a Galaxy S2 (no lawsuit bickering please...)
The last HTC Phone I had was the Sensation and I loved most of it (still no Mac support). Very stylish design and such. My only problem was with the unibody design and short battery life.
I thought I'd give Samsung another shot and the current S2 and S3 are incredible phones. If T-Mobile had the much better One X as opposed to the One S, I'd have one without question.
Mac support can be achieved by using "Missing Sync" for Android devices. Which will sync your DRM free music from iTunes along with photos in iPhoto.
You got a great phone, Android devices have had a bumpy road over the years and yesterday is no exception, but life goes on in the technology world. Android and iOS will still thrive and BlackBerry phones may end up making a comeback if RIM can shake the boring image they have a stigma with. Not sure what will become of Samsung but I wouldn't mind an update that gives me stock ICS or Jelly Bean.
The chase is always fun and the ability to customize nearly every part of an Android phone makes it truly yours instead of having to conform to what Apple offers.
