In other words: no more post-purchase upgrades. The late 2014 update adds dual Thunderbolt ports and faster 802.11ac Wi-Fi (as found on the rest of the current Mac line), but the RAM, which was previously user-accessible, is now permanently soldered to the motherboard.

Two more-expensive base configurations include faster Core i5 CPUs, with a dual-core Core i7 as a extra-cost add-on on top of that. The processor in the $499 model (£399 in the UK and AU$619 in Australia) is a dual-core, low-voltage fourth-generation Intel Core i5.
