Since December 2008 I’ve been using the same Dell 30″ display. Today I upgraded to a Samsung 34″ curved display in anticipation of getting a new MacBook tomorrow. I might have been able to get the dual-link DVI to talk to an HDMI port via a variety of dongles and adapters, but a native HDMI port does make things simpler. My 2012 15″ MacBook Pro drives it nicely, as should the MacBook1.
I like the curved screen; it does not feel like a gimmick. It’s fairly subtle and works nicely. I do miss the extra height a little from the 30″, but the extra width is really quite nice. I can set up two code windows plus a browser and see all three at once. Not to mention the built-in laptop screen for other odds and ends. I expect I’ll be using Spaces quite a bit on the smaller laptop screen, I wonder if I’ll continue to toggle between using them while mobile and not using them while plugged in at my desk or go all-in and use them with the external monitor as well. Time will tell.
