Pretty thin huh? I just found out some more details about the new MacBook Air. Apparently this little sucker  has a sealed, non-user-replaceable battery, and if you have ever used a Mac Laptop means ignorantly lower output of power over a short amount of time. Bottom line – how much is it going to cost to replace the batter and how long does it last in the first place? Answers are coming.

The MacWorld convention is happening today in San Francisco. Steve Jobs will undoubtedly release some new sort of gadget that will blow people away. Stay tuned into NerdGrind for updates throughout the day.
