When Apple relaunched .Mac as MobileMe, I thought this was the .Mac we all were waiting for. Started out pretty rocky. Then I thought they fixed all the issues.
Issues are still there. Constant syncing issues still linger on. Don't take my word for it, visit the Apple MobileMe Discussion forum.

We all have seen the many different lighter apps on the iTunes app store. I normally wouldn't even give these apps the time of day.
Then I read some of the user reviews on iTunes for the iLightr. I decided to fork out the $0.99 for it. Believe it or not, I'm having a lot of fun with it. Another app like the Koi Pond that you can show your friends and they can oooh and ahhhhh over it.
The ilightr makes good use of the iPhones accelerometer, good graphics and realistic sound effects that makes the whole experience that much more fun.

In preparation for my first iphone I plan on getting this week I wanted a way to make my mail management easier to use and be the same on both of my Mac and my iPhone. I knew IMAP was going to be the solution but had to figure out how I was going to do it.

Safari is my default web browser on my mac. Recently I will log into sites like Twitter for instance and then Safari would drop the cookies. I will stay logged in for awhile then without knowing why I would have to re-log back in. But it wouldn't drop every cookie, just a few of them. I looked all throughout my settings and couldn't see any reason why this should happen.
