After trying really hard to use an ipad as a work tool for the most mundane tasks since the very first generation, I'm back for good on an 11" MBA and not looking back. Now that the battery life is 7h+ there's no real reason to carry the awkward tablet & keyboard combo and the ipad collects dust as a hi-end ebook reader.
Agreed. I tried the iPad + external keyboard combo for awhile, but after getting an 11" MBA and using my smartphone for things that I can do completely handsfree (like Skype calls), my iPad has fallen by the wayside for the most part and only comes out for reading comics and PDFs.
