OS Performance — Snow Leopard, Windows 7, and Ubuntu 9.10
BeckySharp writes "With the nearly simultaneous release of Apple's Mac OS X 10.6 'Snow Leopard' (available right now) and Microsoft's Windows 7 (available Oct. 22), you get the inevitable debate: Which is the better operating system, Windows 7 or Snow Leopard? To help determine that, Computerworld's Preston Gralla put both operating systems through their paces, selected categories for a head-to-head competition, and then chose a winner in each category." Relatedly, Phoronix has posted Snow Leopard vs. Ubuntu 9.10 benchmarks. They ran tests from ray tracing to 3D gaming to compilation. Their tests show Ubuntu 9.10 winning a number of the tests, but there are some slowdowns in performance and still multiple wins in favor of Snow Leopard, so the end result is mixed.
The most thoughtful article I read that truly explains what the technical tradeoffs are with dock/taskbar design: here.
On a similar topic, if you want to work on the home page GUI for Android, there is an on-going project as well.
The good news for consumers is that both Windows 7 and Snow Leopard are great-looking OS. Computerworld is just wrong to give a point to Apple on price :-)
The article linked to in the quote block is a terrible little summary of Snow Leopard and Windows 7, split unnecessarily over 5 pages, with nary a benchmark to be seen. Most of the comparisons are subjective, vague, and really not very useful to anyone.
Apple has confirmed that you can install the $30 upgrade version on top of Tiger.
At an Apple store I asked if the $30 dollar was an upgrade or a full install disk. I was told it was a full install disk and no copy of leopard or even tiger was required. I installed it successfully on my sisters computer AFTER wiping it clean (Read: no previously purchased OS installed.) It is a full blown OS for only $30 (not an upgrade disk.) They do sell a more expensive copy that comes bundled with iLife and iWork.
