comment How can I digitize scanned sketches similar to how Preview's signature feature does?
Recommend Vector Magic as well. Works quickly and can deliver good results in a bunch of formats. Clear, high-quality input works best

comment Is a 3-5 second delay normal for a Retina MacBook Pro to wake up from sleep?
I've actually just went and set the hibernatemode after the update and I still wake instantly.

comment How to set screen resolution with a keyboard shortcut on Retina MBP?
Beautiful, exactly what I'm looking for.

comment How can I prevent my Mac from periodically whooshing at me?
I'd describe the "Sent Mail" sound as a "Whoosh"…you don't have anything stuck in your Outbox, do you?

comment Is there a similarly fast alternative to Crtl + Shift + Eject for new Macbook that lack eject keys?
The MBP10,1 is the Retina MBP with no eject button. Yes, I'm on ML. But I've rebooted my system since posting the answer, and it now works. ML bug, probably.

Unfortunately, SwitchResX doesn't seem to work—it doesn't save my display sets and the keyboard shortcuts don't do anything.

comment Which resolutions does the Retina MacBook Pro support, and how?
2560x1920 would be a software mode, which is then scaled to fit the display. It's been stated and verified all over the Internet that the screen physically has 2880x1880 pixels. The hardware only supports that; scaling is done in the OS/graphics drivers = software.

comment Battery cycles for rMBP and recharges?
It is, but the Intel chip should handle the second display fine: arstechnica.com/business/2012/04/… It also depends on the resolutions of the screens. If you have the MBP set to the 1920x1200 setting and you're plugging in a 27" inch cinema display, that's almost 13 million pixels, so you'd want the nVidia. But at 1440x900 + 1080p display, the Intel chip should be fine.

Dynamic switching is what the OS does—it uses the Intel chip, which consumers (much) less power, when you're not doing anything graphics-intensive, and only fires up the nVidia chip when its power is needed. Dynamic switching will keep your power bill down. ;)

comment Is it possible to enable 1.5x scaling using HiDPI on OS X?
On a side note, I've never understood the need to use TVs as displays. The dot pitch means that if you're close enough to read UI text everything's pixelated, and if you're far away to not see pixels you can't read the UI. Get a proper $100–$150 display if possible.
