Need Your Help with opinions on CodeIgniter

[eluser]David Mitchell[/eluser]
Hi, Guys.
I am currently studying Website Development at the University of Bolton and am doing my final dissertation on the features, usability and comparison of 3 of the top 5 PHP Frameworks (CodeIgniter, CakePHP, PHPDevShell) and would be very pleased if you could spent 2 minutes to fill in this short questionnaire which will help my investigation and research further into Frameworks.
