iPage offers a customized version of cPanel referred to as vDeck. This control panel is very flexible, intuitive and shares many similarities with cPanel.
The upsides to using the vDeck Control Panel include a consistent user interface (as well as the ability to customize your UI with custom themes), fully extensible using supported modules, and features that make it easier to manage multiple websites simultaneously.
Though it has a steeper learning curve than cPanel, vDeck is a great option for the more professional website owner, such as a business owner.
