So I've just purchased a secondhand G4 iMac with the following specs (which hasn't been delivered yet). APPLE iMAC 800 G4 (15in TFT LCD, 256MB RAM, 60GB HD) SPECIFICATIONS Processor Type: PowerPC 7450 (G4) 1. Processor Speed: 800 MHz FPU (Integrated): PowerPC 7450 (G4) 1. System Bus Speed: 100 MHz (8:1) ROM Size: 1 MB 2. Data Path: 128-bit Level 1 Cache: 64k Level 2 Cache: 256k (on-chip) 3. RAM Type: 8ns PC133 SDRAM 4. VRAM Type: DDR Video RAM 5. Installed RAM: 256 MB Maximum RAM: 1.0 GB Standard VRAM: 32 MB Maximum VRAM: 32 MB Ram Slots: 2 6. Installed Hard Drives: 60.0 GB Standard SuperDrive: 2X/6X/8X/4X/24X 7. Standard Modem: 56.6k (internal) Standard Ethernet: 10/100Base-T Case Type: All-in-One 8. Form Factor: iMac (Flat-Panel) 8. Exp. Slots: AirPort. Exp. Bays (Free): None. Supported MacOS: 9.2, X Dimensions: 12.95 x 15.1 x 10.6 10. Net Weight: approx 10kg (21.2 lbs.) Notes: 1. The PPC G4 includes the AltiVec "Velocity Engine" vector processor. 2. Boot ROM is roughly 1 MB, other instructions are loaded into RAM. 3. 256k on-chip level 2 cache runs at processor speed (800 MHz). 4. Noninterleaved, 168-pin, 64-bit-wide 8ns PC133 SDRAM (3.3v). 5. NVIDIA GeForce4 MX video card with 32 MB of DDR RAM. 6. One factory-installed DIMM and one user-upgradable SO-DIMM slot. 7. Burn DVD-R at 2X, read DVD at 6X, burn CD at 8X/4X, read CD at 24X. 8. Gorgeous 10.5" half-sphere, ice white case with a chromed stainless steel neck that supports the display. 9. 15.0" TFT active-matrix color display (1024x768 native resolution). 10. Minimum - in inches, height x width x depth (Max: 20.0 x 16.3 x 16.3). However I've done some reading (that I should have done before) and realised that it doesn't come with Airport - seems to be an optional feature that by my reading above it doesn't have installed). Now I could get an external USB dongle to do this, however it seems that this requires USB2... So does anyone know if this G4 comes with USB2? I also want to know this because of the possible drop in transfer speeds with the iPod Nano that I currently have.
