How has your atrix held up hardware wise?
It has held up really well. I have an Otterbox Defender case on it because I've always had them on all my iPhones. It protects the phone well. I haven't had any issues with the Atrix, except the fingerprint reader. You have to be exact when waking the phone with a fingerprint. If you do it sideways, it fails. If you do it too short, it fails. It can be a pain but it vibrates twice to say bad swipe, once to say good so you can do it without even looking. It still beats swiping the finger and entering a code. You don't even have to have a code or fingerprint, I do it to stop my kids from messing with my phone.
How is battery life like compared to the iphones?
It is about equal. If you get it, you'll notice less battery life at first. The reason is that people always use a new phone more at first. You'll be downloading apps, playing with Android. The battery lasts plenty but it will die if used a lot, like any phone. It has the biggest capacity battery of any other Android phone I'm aware of, over 1900 mAh (I may've put that incorrectly).
I read that atrix will get 2.3 soon. Do you thing anymore updates after that one to 2.4 maybe?
I do think it'll get 2.3 in July and 2.4 sometime in the future. Even though it came out in February, the specs are still better than some phones coming out now. The 1 GB of RAM seems to be pretty unique, only the highest end phones get it. I see new phones with 512 and I'm glad I got the Atrix. The RAM, graphics and dual core pretty much "future proof" us well.
Did you compare to iphone 4 before getting the Atrix?
I never really seriously considered the iPhone 4 but I looked for a phone with a front facing camera based on the fact that the iPhone 4 has that. I personally decided there wasn't enough of a reason to get an iPhone 4 over a 3GS so I never did.
Is motoblur really that bad?
No. I don't even use it. At the moment I'm using Launcher Pro. I have used ADW EX and Zeam as well. You are not tied to any one brand of home launcher. You don't really even notice the included apps running. People like to pick a flaw and harp on it so they go with MotoBlur and the locked bootloader. I have no desire to run a full custom ROM so a locked bootloader doesn't affect me. I use another launcher so MotoBlur doesn't affect me either.
