I ordered my copy, and the blurb that came back was that they were extremely busy, so there would be a delay.
One week later, the package dropped through my letterbox.
The program installs easily, but you have to register it with Microsoft, otherwise much of it will stop working after 30 days.
You are allowed under the EULA to have it installed on your Home PC, and also your Laptop, but can only use one at any time. You may have to contact Microsoft after installing on Laptop.PC (whichever was last) because the original serial number may come back as 'This product has been registered enough times' (or similar), MS will ask you to read part of the serial number to them, and then give you a long string of characters to type in to validate the licence.
Contacting MS for the laptop serial number was painless and only took a couple of minutes.
Not bad for £17.31
