The service looks great - control panel looks good and covers much of the same stuff as linode, setup is a breeze. I think the design of the panel is nice and clear. One thing I would recommend is that you guide customers not to leave root login open, and perhaps request a key during setup instead (at least as an option), as leaving ssh open on port 22 and accessible by root by default is going to leave a lot of your servers more vulnerable than they should be, particularly if people change the root password to something silly.
Do you offer DNS? That'd be a nice addition if not, haven't looked around fully so might have missed it.
I'll be testing this out in a small way for personal projects, but it looks comparable to something like Linode IF you can match their uptime and service, which is a really hard thing to do. Obviously I wouldn't trust it for anything important until I and many others have tested it for quite some time and found any issues, so you might find it difficult to collect serious customers at first, but I think this offer is a great way to entice people to try it out.
I like that backups have a very low price per hour - £0,000056
A few tiny localisation hints:
Customers in the english speaking world will find commas as separators on prices confusing.
There is no verb 'backuping' that should be backing up - I'm trying one now!
