Just bought myself a new iMac with a 27 inch screen. A thing of beauty. After a decade or more of working from laptop computers (or notebooks..what are they called now, anyway?) I decided to have one gi-normous heavy desktop again and synch the important content using SugarSynch and Dropbox. It’s the cloud baybee! And not lugging my MacBook around has made my back happier.
One thing I have learned is that desktop real estate is a big deal: a large monitor, or two small monitors (say a notebook and a 20 incher) allows me to write more efficiently: my manuscript and bibliography open, and Google Scholar and Devonthink lurking ready to pitch in. And monitors are comparatively cheap nowadays.
I had a choice between two versions of the iMac, a 2.7Ghz and 3.1Ghz model for about a $350 more. When I asked the Apple guy if it really made much of a difference, he scrunched up his face for a millisecond and said, “No. Not really”.
