No problems here
Although I am no fan of Microsoft or their products, that has not stopped me from using Hotmail since 1998. I've had only the one account there since then, and it currently gets between 200-300 spams per DAY, most of which end up in the Junk folder - only about 20-30 spams per day make it into my inbox. It is a matter of a few seconds to tick the obvious ones and then click Delete. Were I to do a "time and motion study" of all the "few seconds" I've spent ticking and deleting spam, it would probably come out to a total of maybe a couple of hundred hours of my life lost dealing with spam in this fashion.
Big deal. How much of my life have I spent twiddling my thumbs at my desk, or worse, spending company time posting comments like this in forums and blogs around the net? (I'm posting this from work, for example). It profits me nothing to do so. But it helps me relax before tackling another problem, and I do a better job because I've posted something to let off some steam and I'm more relaxed and de-stressed because of it. So counting lost seconds to me is a pointless exercise.
Hotmail for me is a catch-all account. My "home" ISP-provided email I don't use, except for family and friends I know IRL, and I never give that address out on the Internet. The reason is that to read my ISP email, I need to use a mail client, which has to download all the email from the server before I can read it - so spam here would actually cost me money in bandwidth. Hotmail, on the other hand, doesn't use any bandwidth (other than to display as a web page) or require me to download email first, so I can delete any spam without ever having to download or read it.
Any time a website demands my email in return for some information, to post a comment or to download a file, I use my Hotmail address. The only exception is my bank, because I don't trust a freemail provider with any information that might pass between my bank and myself. And my bank can be trusted to keep my home email private, because there are laws in place relating to banks and security of information above and beyond mainstream privacy laws.
I also use my Hotmail address as a point of contact for people I deal with on the Internet, and for people who have the bad habit of bulk-forwarding jokes and such. Because I use my Hotmail address this way, I EXPECT to get loads of spam - that's the nature of the internet. To me, throwing out spam is just the cyberspace equivalent of walking around all the A-frame signs and ignoring spruikers at my local shopping centre when all I want is to get some bread and milk. It goes with the territory.
Finally, I have never had any problems with receiving emails from anybody at Hotmail. Every time I've signed up at a site that requires me to respond to an email to "validate my account", I've gotten the email. True, the activation email ends up in the junk folder as often as not, but a quick look in that folder soon turns it up, I add it to my Safe list, click its activation link, and that's that. Afterwards all emails from that domain go into my Inbox. If emails are "disappearing", check your Junk mail settings. I never set these to automatically delete a mail, even if it's got fifty repetitions of the words "viagra" and "penis enlargement" in it. All incoming mail is stored against the possibility it may be genuine, and dumped once I've determined it's not. As a result, I've never missed or lost an email I wanted to keep.
So Hotmail suits me fine for the purposes I use it for. It costs me nothing, it saves me downloading spam at my home email, and I can access it anywhere. I've used it for over 8 years without any problems. And as long as it exists and continues to fill these basic requirements, I'll continue using it.
