How do you find the Poker2? I have one and tried it for 6 months. But I always felt cramped, hard to explain. Might be because it is brown switches, where I use blues for all my other keyboards.
Have a look at https://craftcms.com I have used it a couple of time. What I really like about it is you have complete control of what gets to edit/add. And interface for the client is as simple or complex as needed.
Have you tried http://buildwithcraft.com/ as an alternative CMS. I use it for all my client sites. The ability to make client specific fields on a "page" basis and a templating system that stays out of our way it is the best CMS I have worked with.
