Agreed. I use dashlane password manager and I can log in on the website to retrieve my passwords. Apple should use iCloud this way and allow you to access your keychain data by logging in to iCloud.com.
Finally, a fair review of a competitor's product. I personally dislike the surface but I like Win 7 and it's nice to see a fair review here. If you don't want to read it, then don't. It's nice to hear how the competition fairs against Apple's products.
Holy cow! That's a lot of detectors! Our 2 floor (+ basement) 2000 sq ft home only needs 3 detectors - 1 on each level. And only 1 thermostat. When I get my own place, I would love to get a Nest product.
I have found that typing is slightly more delayed, and Safari is quite slow at opening. Some apps crash now and then, but my battery life is slightly better with the upgrade. Overall it works well and I'm very happy, but I do miss not getting some of the features, like parallax and cool weather animations.
