What do you mean by "work smoother"? If you compare the two side by side that's not the case at all, and I've done so. For me iOS on any hardware is still crippled by lack of proper multitasking and background processes. A handful of specific background processing API's simply isn't good enough IMO. You still don't have anything working in conjunction with anything else the way Android does because processes get frozen rather than continue to operate. It's probably good enough for most people but it's not the way that I prefer to operate and everytime I try to use iOS it frustrates me within 5 minutes. Open an app. Press home. Open another app. Press home. Open another app. Press home. It's no wonder dogs, cats, and month-old babies can use it.
Sure, there might be a whole bunch of great games and random ass apps - there are on both platforms. But when it comes to the essentials - Gmail, Gtalk, Navigation, YouTube, G+, Google Calendar, YouTube, Latitude, Docs, Google Reader..... iOS lags far behind in functionality. Even some third party apps that used to be inferior on Android, have now not only caught up but actually surpassed their iOS versions, like Foursquare which I use so heavily that's on my home screen. Spotify and obviously Google Music are superior on Android.
All of those are things I use literally multiple times a day and all on my homescreens.
If I was looking for fluidity I'd go with WP7. But that means nothing because the core services are shit. Just like the core services on iOS are shit. iTunes? gimme a fuckin break, it's a piece of shit.
I don't see Apple as a software company. They're a hardware company that happens to make operating systems for their products. The way I see it, let the great hardware companies of the world make great hardware. Nobody is fucking with Samsung when it comes to hardware. Nobody. Let the great software companies of the world (like Google) make great software. When it comes to web apps Google have the game tied up. They're fighting a war on social with facebook. But nothing else has a competitor, there's no competitor for Search, or Maps, or YouTube, or Gmail. So let the great hardware people and the great software people work together and share the wealth. No need to be a dictatorial control freak.
I see zero innovation coming from Apple. There's no freedom, live in the walled garden and see what they allow you to see, the bits of innovation that trickle down, usually a year or two later.
As far as the G2X, who the fuck cares about official updates when things like CyanogenMod exist? As with every other device they support, it'll have a blazingly fast ICS when CM9 comes out in a month or so. If you rely on official updates from carriers of course you're gonna have a shorter life cycle. But you're locked in, that's an Apple-esque way of thinking. Luckily, you have a choice. From an "official" perspective the G1 was dead at 1.6. I used it for another 16 months after that and by the time I replaced it, it was running 2.2, and it was running it very well. It went on to run 2.3 pretty well, too.
