If you want a trapped-in-an-MMO-anime along a similar vein that does have a magic system and actual spellcasting, I'd recommend checking out Log Horizon. (Actually I'd recommend it above SAO in any event, as it's better by several miles. SAO has... rather serious problems that I won't go into here.)
Technically very little magic, although it has skills that are effectively magical in ability. Case in point, our hero stands there at one point letting multiple characters just whale on him, and calmly comments that his regeneration is so high they will never take off more HP in a round than he recovers. So a lot of "not magic" magic.
