Bemoaning the fact that those new slimline iMacs werent compatible with your VESA mounts? Well, the problem has now been (kind of) solved, with Apples online store adding the option to buy its desktop models with built-in VESA mount adapters. Youll have to pay for that reclaimed deskspace, however, with $40 added to the prices of both the 21.5-inch and 27-inch families. Youll also need to purchase the stand separately, although your old VESA arms will be compatible. Alas, if youve already paid up for your new iMac, theres still no word on any transformation kits just yet
