I had a look at this site. While some of the features 'look interesting' there is a definite lack of information. Unlimited bandwith, unlimited disk space, unlimited blah blah blah is nice and everything BUT meaningless these days. More importantly, what % of CPU may a site consume before it is suspended? How much RAM in the boxes? As well...
Do you have fully redundant data centers?
What is the uptime?
Do you provide FTP/SFTP, PHP, Perl, SSI, .htaccess, telnet, SSH, MySQL, crontabs?
What is tech support like?
What modules are enabled on Apache? (assuming Apache is even offered)
