Wow, those ET's look nice, don't they? But they seem to suffer the great problem of planars, especially magnetic planars - lack of dispersion. And, with such a small planar but wide frequency driver, they suffer from a lack of both horizontal and vertical dispersion. But hey, if you are sitting close and still at a computer then I guess that doesn't matter. But that directionality may give you fits as you move the chair around just to get into it; I think you'll find yourself constantly readjusting the satellites every time you sit down to compensate for your exact seating position.
But, being ET's, the sound may be worth it. They are really pretty, being ET I'm sure nicely made, and considering all not excessively expensive.
