While I love my Galaxy S, I wish things wouldn't change quite so fast. It seems like every time I get a gadget, the new version comes out 3 months later and tempts me to spend more money.
Thankfully, my Galaxy S is still doing everything I want, so it's not -too- tempting.
As soon as GS II came out, I bought a Galaxy S, the first version -- that's how I like my phones, kick-ass and cheap.
I'll probably change it anyway in a year or two, so why bother paying more for the newer version. I also have an iPhone 3GS, and as long as the battery doesn't die on me and as long the latest iOS works, I won't upgrade.
Apple users (myself included) can be certain to a high degree of accuracy that when buying a newly released Apple iDevice, it'll be "the best on the market" (the market here being defined as Apple iDevices from the same family) until about a year later. As opposed to the Android world where you know that something better will be coming in a few weeks, and you don't have the shiniest, newest thing.
So I'm happy to forego the incremental one-ups from the Android world and know that I have the best device, and that if I want to get the new one next year, that'll be the newest and shiniest for a whole year too.*
If you're happy living in an iWorld, you get a clear step function where you know what step you're standing on and about when the next step will come. This doesn't result in slower progress (in my opinion), it's just a different shape than the more smooth sloped progression in the Android world.
* And sometimes, as with the iPad/iPad 2, I'm happy with what I have and don't feel compelled to have the latest and greatest.
I have a Galaxy S and find Android to be very buggy and slow. This is my first touch screen phone so maybe I'm just not used to how they are, but my old blackberry rarely had these issues.
Are you still on Froyo? Gingerbread for the Galaxy made things a lot smoother. (even the first update to the original release firmware made a noticeable difference. See which version you've got.)
Android is buggy and slow by nature, but 2.3 Gingerbread has significantly improved performance over 2.2 Froyo. I hope they clean up all the bugs and performance problems for 4.0 instead of piling on features.
