What do you say about something that "just works" ? That is what EFI-X does. I built a machine with components only from the (short) HCL, connected the EFI-X module to a spare motherboard USB header, switched on and then installed from a retail Mac OSX X 10.5 DVD.

Once past the EFI-X boot screen, it is just like using a real Mac. Compared to the Power Mac G5, it is very fast, and somewhat quieter. There's no hacking, disabling, fiddling, modifying or other faffing about required, even updates to OS X install from Software Update as they would on a real Mac.

No product is perfect, but the limitations are few and minor and include:

  • The EFI-X booter is not Open Firmware, and therefore cannot boot from Firewire (yet.)
  • Windows and OS X can't share a single drive due to the different partitioning schemes required (MBR vs GPT)
  • Booting into the EFI-X environment adds about 10 seconds to the bootup process.
  • Audio doesn't automatically switch between line-out and headphone out when you plug headphones in.
  • Scraping the bottom of the barrel here .. System Profiler shows the graphics card as 256 Mb when it is actually 512 Mb ... cosmetic only.

So for $1000, you can have your very own yum cha brand Mac Pro.

So now Street View has been enabled for many Australian cities and suburbs. I have a suspicion that the Street View car might've been doing some wardriving at the same time, because my entirely GPS-less iPod Touch can now locate me when at home (in the suburbs) to a high degree of precision. "Locate Me" on the Touch used to only work in the CBD, and not that accurately either.

It's too big. My current laptop is the last of the PowerBook G4 12" models -- 1.5 GHz G4. Let's look how it stacks up to the Air.
