Today Apple announced the Mac Book Air and new ultra-slim laptop computer. Weighing only 3 pounds, this notebook is like someone flattened a Mac Book. Here are a couple of deal breakers for me with the Mac Book Air:

• No user replaceable battery
• No Firewire
• No DVD player (or optical drive
• No built in Ethernet connector
• $1800 starting price
• Only one usb port
• Only 1.6GHz processor speed (the slowest Mac Book is 2 GHz)
• Only a 4200 RPM hardrive (pretty slow)

On the other hand, it is a cute little computer that would be quite a bit more comfortable hauling around all day in my backpack. I am still. however, exceptionally worried about the built in battery. I’ve had two batteries on my iBook be recalled because of their poof-potential. I would hate to have to go through the trouble of servicing my laptop or watching it explode if ever the battery were to explode.
