The problem as Microsoft and Tesco have found the hard way is that when you love shareholders and treat your customers with total contempt, there comes a tipping point especially when there is more competition around (with MS; Apple, Google and Tesco; Aldi, Lidl) that those customers do the grand salute as they move to rivals and because of the p-take they have previously endured they are never tempted back.

Although our local Tesco is one of the biggest in the country and the closest Supermarket to me, I only very rarely use it (every 2-3 months) to buy what I can't get at our, not so local, Aldi and Lidl.
Personally, it will be a big day of celebration when I never, ever, have to use another Microsoft product ever again. IMO very poorly designed, poorly programmed, abysmal, perverse, convoluted must do it 'the Microsoft way' interfaces, which has IMO been the biggest obstruction to the advance of computing ever since they monopolised PCs back in the 1980's. Even when they take over very fine products like Skype within 6 to 12 months it has had the 'Microsoft makeover', which makes it b-awful, to the point where, several times, I have looked round to try to find a rival product. Not to mention it now has a memory leak so it grows from 16MB (a much bigger footprint than it used to have) up to 250 to 500Mb over the space of 24 hours where it seems to create advertising buffer space and never delete it! I won't even mention their perverse improved image transfer and saving system, where they have improved things much worse.
