This is just a quick a post to provide a little class for Windows 8 Store app development. The SystemInformation class gathers some useful information about the current system and can dump those as a string. I usually have such a class for all the platforms I work on and it's very helpful for logging and error analysis, but it also serves as a list of all available system information which are scattered in different APIs. The info can also be used to dynamically adapt the app, etc.
Here's the code I have so far, you can also download the complete class
here.
public static async Task Dump(bool shouldDumpCompleteDeviceInfos = false)
{
var builder = new StringBuilder();
var packageId = Windows.ApplicationModel.Package.Current.Id;
var clientDeviceInformation = new EasClientDeviceInformation();
// Get hardware Id
var token = HardwareIdentification.GetPackageSpecificToken(null);
var stream = token.Id.AsStream();
string hardwareId;
using (var reader = new BinaryReader(stream))
{
var bytes = reader.ReadBytes((int)stream.Length);
hardwareId = BitConverter.ToString(bytes);
}

If you know more system information Windows 8 APIs that listing is missing, please add a comment.
The Windows Phone 8 SDK is now available and with that WriteableBitmapEx was updated too. The performance of the WinRT XAML version was also improved dramatically and an update is highly recommended.
