The MacBook Air got a nice spec bump and $100 trimmed off of all models except the base $999. Also, the lineup got a much needed bump in memory up to 4 GB standard and optional 8 GB. With the addition of Ivy Bridge, HD Graphics 4000 also provide up to 60% faster graphics performance. Available in 11-inch and 13-inch models, options are few but important for Apple's super portable laptop.
