This looks really good, definitely going to pick it up when 8 comes out.
Playing with the 8 previews, I've had problems with the density of not-called-metro-anymore interfaces and a mouse. 90% of this looks workable, and hopefully the rest will follow.
Great that you care about this, but the environmental consequences have been largely invisible to Americans for many years. Be it CO2 or destroyed ecosystems in every oil producing country, the damage is largely done.
I'd hardly blame this rag for the oversight at this point.
Yeah, that's why they're supported in PostgreSQL, MySQL, Oracle, DB2, MSSQL, even SQLite... Multi-dimensional data isn't restricted to the world of GIS, and B-Trees are not up to the task.
The next three by units (Bridgestone, Michelin, Goodyear) all do commercial/industrial/aviation, I think Goodyear falls out a bit at the top end. 400 tonne trucks use Bridgestone/Michelin, the Airbus A380 uses Bridgestone, for what it's worth.
IE8 and Android 2.4 don't support it for one, but it does seem SVG has never really had traction. I've heard SVG has poorer rendering performance in most browsers (I'm not actually sure if that's true), and that some folks feel it makes it easier for their assets to be copied.
