The Memory, Graphics Card and Add-Ons
Lenovo uses a Santa Rosa platform with its GM965 chipset. So the X300 does use two channel DDR2-667 (2 GB included) memory and a GMA X3100 graphics controller.
Lenovo offers DDR2-667 for the X300. By default the machine is delivered with 2 GB of RAM memory (two 1 GB modules). Unlike other ultra-portable laptops, the memory is housed in two classic SO-DIMM slots so adding up to 4 GB of extra memory is very easy.
The Graphics Card
The graphics card is a classic GMA X3100. However, ultra-portable laptops have to use a decelerated version of the X3100, so while the normal version runs at 250 MHz on battery with a maximum speed of 667 MHz, the X300’s speed is 166 MHz on a battery charge and a maximum of 500 MHz. A few more minutes of battery life is achieved through the reduction of performance.
Let’s be clear, the GMA X300 does not in any way make the X300 a gaming machine, and the machine’s screen resolution (at 1440x900) doesn’t at all help Intel’s controller. It’s enough for an application like Google Earth or Aero (Windows Vista’s interface), but that’s about all.
It is possible to add extension cards to the X300, such as flash memory devices and MiniCards. In addition to the 1x (250 MB/s) PCI-Express/Mini Card slot, there is also a USB 2.0 (60 MB/s) port. The X300 we tested came with a Wi-Fi card (Intel 4915AGN), a 3G Sierra USB module card (Sierra, USB) and an empty slot that could accommodate a WiMAX or wireless USB device.
The air is so limiting (you can't even change the battery- its an ultraportable without flexible battery options!
Don't get me wrong; I think the X300 is a fantastic machine. It's a bummer that they didn't give it a good screen, and I hope that some of the quality issues with recent Lenovos don't manifest with this one, because it's an amazing engineering accomplishment. It has several features (especially WWAN and much better expandability/connectivity) that I really wish the MBA hadn't compromised on. Then again, aesthetically there's no comparing the two; the MBA is simply an amazingly desirable object, where the X300 just comes across as...competent. Whether that matters to you or not is purely personal.
The MBA is 4400 AUD with the solid drive, I can get a Mtron 64GB for about 1400 AUD, making my Sony cost about 3900 AUD. Battery life? My non-extended battery can play two DVD's without needing a charge, (barely) or just about enough time to get me from SYD to HI :-)
they should have installed vista on the macbook or MAC OSX on the x300
that would give a proper benchmark of the hardware.
