There has been a lot of complaining about the lack of upgradability with Apples recent products. It began with batteries in the iPod, iPhone and Macbooks. It arose again when the MacBook Air was launched. The most recent target is the new retina display MacBook Pro. iFixit really doesn't like the new design, in part no doubt because Apple's choices directly affect their bottom line.
Nick Chaves takes to his blog to lend his voice to the issue. I'm inclined to agree with his opinion even though part of me will miss the ability to upgrade components later. I've done it numerous times with hard drives, RAM and most recently by removing the optical drive in my MacBook Pro to add an SSD. Most consumers however, will never undertake such a task.
Apple is once again catering to the 80%. Take an extra minute before you order your new laptop and be sure to order it the way you want to use it. Then just use it and enjoy all the benefits Apple's current design decisions yield.
