I will probably need to purchase a new laptop this year as my trusty Asus UL30A is literally falling apart (pieces of plastic have started falling apart and the case is coming apart too.

For a variety of reasons, I expect that we will see a new release of the Macbook Air line in Q3 of 2012, and normally I would wait to purchase the new model until it comes out so that I can maximize my value of the product's lifecycle, but I was wondering if, due to hardware compatibility issues, people might recommend buying an Apple product later in the product cycle to account for hardware issues in Apple products. Any advice?
