BurmaYank. How about a Fresnel lens effect? Just pondering.
I handed that 27-inch 2010 iMac down to my wife. In fact, she is using it in Target Display Mode with her MacBook Air. I wrote about it on 4 Nov 2014. http://www.macobserver.com/tmo/article/connect-a-macbook-to-an-imacs-display-with-target-display-mode
Brutno: Right. I fixed it! Thanks.
mjtomlin: I don't remember that. Checking....
furbies: I remember doing that. Thanks for the memories.
Mr. Christian: Thanks for letting us know!
JoelS. I have had similar thoughts about reasonably priced hardware upgrades. Go into the Apple store in two years, pay $150, and get an internal upgrade. You keep your watch strap of choice, the outer metal shell, and the crystal. But it's just a fanciful notion at this point.
Sandro, Dave, Mark: All have been added. Thanks!
mhikl: Thank you sir.
furbies: Ahhh.... THAT would be in the post-Christmas category.
