Heres my thoughts from the ipad competitor news post on the front page:
As someone that recently (2 weeks ago) jumped from an iPhone4 to a Nexus S, I wanted to put out there my thoughts on the comparison of iOS vs Android 2.3.3 Gingerbread.
Anyone who says one is better than the other one is full of crap. There are things Android does great and there are things that iOS does great. Neither one is clearly better at everything than the other, and both are competent.
Android is much more flexible in the customization department, however this comes at a stark stability disadvantage. I've had quite a few (4-5 in 2 weeks) hard locks, or instances where my home screens wouldn't load that required a battery pull. One night I got up to take the dog out, and glanced at my phone on the night stand. It was the screen was half lit up and garbled. I had to do a battery pull to get it to reboot properly. The phone was literally sitting at a locked home screen for at least a few hours before it did this, so it wasn't anything funky I was doing. Battery life is also less than desirable, but this is more of a phone thing than a platform thing.
However, the notifications are much better, I'm able to replace stock apps that provide the basic functionality of the phone with ones of my liking or needs.
On the other hand, iOS is more locked down, but the notifications system is god awful, there's no way to properly replace or remove included apps that you require more functionality from (SMS, e-mail), but in an un-jailbroken state, I've never had an app take down the entire OS.
In the end, both are great but both need a lot of work to be perfect.
I will say that I've since flashed from NSCollab 17 back to a 100% stock firmware on Monday, and my hardlock and reboot issues have gone away. My battery life has improved somewhat, but its still not nearly on par with my iPhone 4. My wife has had no complaints yet, and I had to pry her iPhone 3GS out of hands. If I had the choice of getting T-Mobile pricing and keeping my iPhone, I would have. The iPhone 4, other than the notifications issues, really did everything I could think of that I wanted a phone to do. AT&T ruined it for me. Verizon pricing is no better. Same features, with more minutes, going to T-Mobile is $115 a month after taxes for 2. On AT&T it was $187. Saving $70 a month is no joke.
Having twins has dramatically reduced the time I have to nerd out.
