Lion. It's the best macbook pro I have ever gotten.

I've only ever had one other macbook pro (besides my 2010 iMac), the 2009 13 inch base model. The dictation is extremely accurate and really responsive. It's completely silent. I've only heard the fans once when it was updating to lion and installing the smc update afterwards.
The only issue I am having is trying to get the iLife apps to update. For some reason it keeps saying that the updates are for another apple id account but I have only put one id in. The app updates should be for the current id since they came pre-installed. I also had an issue registering it through the automated, first turn on screen. I put in all my information but said "not now" when asked if I wanted to send it because I didn't have wifi at the time. Now that I have wifi, I can't find the file that it said it would create in my home directory which when clicked would send the registration stuff. So as of now I am not sure if it is registered and I think that it not being resitered is causing my issues with the iLife apps. I'll be calling my represenative tonight to see if she can explain the problems and get them fixed.
Besides those two issues, it is awesome!
You'll love yours when you get it.
