It may just be that the person that ordered her lappie (her son I believe) couldn't find the option to order XP, or that it wasn't offered on her particular product. I don't know what the exact circumstances were. Either way she didn't order with XP.
Whilst she's certainly no techie, she isn't unfamiliar with previous editions of Windows, and as a returning user her overwhelming opinion is that practically everything is more difficult with this edition than what she is used to from XP for example.
In terms of ease of use, which has, I would submit moved forwards from one Windows version to another, this represents a step back for MS. Whilst this particular user is distinctly none technical her opinion is as valid as anyone elses with regards to usability.
At those posters who claim that this is the best release ever.....
Being here tends to suggest that you are technical users at the very least, have some respect for those users who lack your technical background and have spent substantial time and money to find that Vista is not the amazing experience the marketeers told them it would be, and that even though they bought in their eyes high spec machines (ie RAM > 1GB, dual core processors etc etc) found that this release runs far worse their old XP/2000/.... machines and is more difficult to actually use.
