I would never buy the Mac Air. Like the Palm Foleo it missed the mark. Like the Foleo, it too is overpriced.
So what if it is thinnest? It's not the lightest ultra-portable. Weight is clearly more important than thickness. Like most Mac products they are only complementary, and you still need something else to get the job done.
What if you just want to take out the battery? I can do it in two seconds on an OLD Dell laptop which has a battery level indicator built in. I can instantly tell the charge level. I can also swap batteries, due to multiple universal bays.
Does Apple do focus groups, questionaires and listen to their buyers? I can't imagine being asked, "Would you like to be able to replace the battery easily?" and answering, "No, I want to have to send my laptop away."
From Apple's own website:
"Long Term Storage
If you dont plan on using your notebook for more than six months, Apple recommends that you remove and store the battery with a 50% charge. If you store a battery when its fully discharged, it could fall into a deep discharge state, which renders it incapable of holding any charge. Conversely, if you store it fully charged for an extended period of time, the battery may experience some loss of battery capacity, meaning it will have a shorter life. Be sure to store the ejected battery at the proper temperature. (See Notebook Temperate Zone.)"
Ultimately, it would be fine for most people if you can easily replace it yourself without warranty hurdles. Most people do not change the battery very often, only when it no longer holds a charge. But sending your notebook to Apple just for a new battery is just plain stupid. The Air must be thin at APPL. Someone please give them oxygen.
