E-mail comparison

Now there are more free mail for us.First Google presented Gmail which it has 1G space,but it is only for the people who are invited.And then Spymac and Yahoo.cn(only in China) followed.But you should invite one friend to active 1G mail.Sequently 163,126 ever presented 1.5G e-mail,and if you have 100000 POPO currency,you can active 2G e-mail.Under the pressure of G mail,Sina follow them to 1.5G in secret,and if you collect 500 point of stamp,you also active 2G mail.Recently UES presented the biggest e-mail.It offer 3G space.It is so crazy.Now let's compare G mail.
Because I haven't been invited by G-mail, it's so pity that the comparison doesn't include G-mail.Let's show the space of these e-mail ,attachment and anti-virus.
Name Space Attachment Anti-Virus
G-mail.com 1G N/A N/A
Spymac.com 1G 10Mb N/A
Yahoo.com.cn 1G 10Mb Norton AntiVirus
163.com 1.5G 30Mb Kaspersky
126.com 1.5G 30Mb Kaspersky
sina.com 1.5G 30Mb N/A
UES(sgies.com) 3G 10Mb N/A
Let's check speed of them.As I live in China, 163,126,sina get the best speed, yahoo,ues,g-mail,spymac follows.And in receiving mail,Sina probably can not receive mail from some foreign countries,because I send an e-mail in UES to sina,sina can not receive.Others don't exist this problem.And when you send an e-mail,sina would add some advertisement in the mail.As for the style ,UES is the best,spymac,sina,163,126,yahoo follows.
As far as I'm concerned,I think these companies sell it by space to attract people.We benefit from them.Perhaps other company will provide more space for e-mail,though we may not use up all the space.
