The Apple Store today kicked off a post-Thanksgiving Monday sale that has swung attention to accessories and some of Apple's secondary services. Audio is a focus and sees Beats' Beatbox speaker dock and Solo HD headphones drop down by $40 and $20 respectively, to $360 and $180. M-Audio's KeyStudio 49 MIDI keyboard has also been discounted from $100 to $70, and Edifier's Prisma E3350 speakers have had their price lowered to $117.
