The email service is a lot like the new GMail that will be coming out (except GMail has keyword search and Spymac does not).
But, aside from the email service, what I really like about Spymac is their webhosting packages. They look very nice.
for $10 a month (or less actually, it can be as low as $7 a month) you can have:
1 free .com, .net, or .org domain
500 MB of space
20 GB bandwidth
10 POP3 accounts
and more.....it lists more details there.....
someone had to beat gmail to the punch
