While Apple has just released the 2014 MacBook Air models, which are now cheaper than ever, interested buyers shouldn’t necessarily purchase one of them just yet, or at least not until they check out all other available Air deals, considering that the new models offer only slight improvements compared to last year’s Airs and that 2012 and 2013 MacBook Air versions are now even cheaper than before. According to AppleInsider, the early 2014 MacBook Airs only show a slight performance boost compared to their predecessors. The new 1.4GHz dual-core Intel Core I5-4260U chip found on base new Air models has scored 2532 in single-core tests and 4781 in multi-core tests performed on the Geekbench platform and available via Primate Labs’ Geekbench
