Got a couple of those Netbook things for Mrs JP and No 1 daughter.
In shop the resident geek came up, seeing two middle aged cretins and started to explain that "IT'S NOT WINDAES AND YOU CANNAE USE WORD AND STUFF ON IT". The wee lassie standing beside him was impressed with his technical knowledge and people skills.
I pointed out that I was well aware of the history of linux and how it was an open source adaptation of Unix, written by a chap called Linus Torsvalds, hence the name. I explained a wee bit about the concept of open source and how it had resulted in a variety of linux flavours. I thanked him for his concern but trusted that he realised I was capable of coming to a decision sans his condescension.
When the wee lassie asked if we were interested in the White or the Blue case I replied "You better give me one of each" she bimbled off just before his cawk fell off.
Mrs JP was mightily amused at the whole episode.
