Updates came down quite quickly because Apple bundled them up into one file; unlike on Windows where it takes an absolute age ;-)
Actually, you're wrong there. With the Windows platform each component supplier can update there drivers at any time and distribute them through Microsoft/Windows update. In addition, I get much better drivers and updates via Windows 7 on my MBA. Not only that, I get about triple or quadruple the performance from my exact same MBA in Windows than I do in OS X for graphics, HD playback, and most importantly Flash.
We all suffer in OS X because Apple is so secretive with their OS code. It means Apple writes every single driver for every component in every Mac. While it saves money for Apple, and encourages Apple to use few components to write less code. The problem is OS X component drivers are so extremely inferior to drivers available on the Windows platform. The best way to install Windows on a Mac is to avoid the Boot Camp driver package. Use Windows update and actual Windows drivers from the component suppliers to get AMAZING performance boosts over anything Apple provides.
Anyone thinking Apple leads in updates and driver support hasn't looked into the bigger picture. In addition, where Microsoft gets a bad wrap with driver support and crashes, it's the component supplier drivers that often cause problems. When a PC is built with solid components, which all include well written drivers, the PC and Windows can provide an excellent experience. This is all proven PRECISELY on Macs. Apple uses very nice components in Macs. It uses a nice CPU, GPU, chipset, WiFi chip, Bluetooth chip, network adapter, drive controller and etc. Where PCs go wrong, especially with low-end PC suppliers and more importantly whitebox custom configured systems, is one or two cheap components with a few badly written drivers and problems happen.
So there is an advantage to using a Mac, but it's not OS X and Apple's drivers... it's the quality line of all medium grade components. Then using the best drivers with those components and a great user experience is nearly a guarantee. Then the user needs to keep away junk printer apps, junk accessories with terribly written Bluetooth or multi-featured mice drivers. The advantage of using OS X is extremely stable drivers, but the disadvantage there is Apple doesn't truly take anything to the limits. Look at OpenCL drivers, or look at the very few GPUs that Apple allows h.264 hardware acceleration from, now not just the 9400m - Apple now allows 320m and 330 GT to performa h.264. However, it also means the 15/17" MBPs have to run their dedicated graphics to do simple h.264 acceleration.
There are advantages and disadvantages to Apple's Macs and OS X operating systems. If one wants extreme stability and very little performance, the OS X can win. If people want great stability and excellent performance, Windows can win. If people want some stability, decent performance, and cheap components, Windows can win. Everything comes at a cost with Apple's Macs. One, higher cost in terms of money. Two, higher cost in terms of stability taking away from performance. And Windows can offer more performance from less costs, and terrible performance from super low cost.
