That's simply not true. As I mentioned above, the MBA costs a student $949. The base model iPad costs $499 (no student discount). That's not even double. So your quote of "three times more" is simply a lie.
And the fact of the matter is that the $949 MBA is many levels above the base model iPad. If you want to try and have a fair comparison, you would compare the $829 iPad, which still isn't nearly as good as the MBA, and costs only $120 less.

Please read it.
First of all, calm down.
My main point was to highlight the price difference. It is easy for people just to say "buy MBA instead of iPad" in these forums. However, I rarely see anyone taking the price difference into account.
