The Logitech Orion Spectrum
I'm sure there are far more knowledgeable people, (gamers/workers) than I who have their own reasons for the board they chose, for the particular style of game play or the way they work. The G810 works for me.
So far it is everything I was looking for when I went searching and more; The Romer-G keys have a shorter stroke than my 7 yr; old MS board and will take a bit getting used to, however I'm improving after only 3 days.
I truly can't call this a con, surely a grand idea and option for many I'm sure, I don't have a use for the majority of the lighting options; Someone with big brains might consider doing a studies on light affected epileptic seizures, trance inducement via light manipulation and vertigo inducement...
