1) I have yet to meet anyone living that would need anywhere near 1Gb of mail space. I save any important emails to CD/floppy.
2) Couldn't really care less about adverts. I buy newspapers, magazines and watch commercial TV channels. OTOH I have had some brilliant deals thanks to adverts :-))
3) Whoever reads my emails is a matter of supreme indifference to me and the cat. Anyone concerned about security will be encrypting their emails or communicating in other ways. My emails are triple dull.
4) People have an imagined right to privacy but in reality they have none in any electronic age. Demanding privacy in today's world is the epitome of naïve idealism. Again, whoever knows my personal details is welcome to them. If they blag my bank/CC details the companies will refund double quick. Having had a spurious flight to Nigeria put on my charge card I know that they refund quickly and £25 extra in my case. So long as I get £25 each time the world and his wife can use my charge card.
5)...er, that's all.
