I love that it's easy as pie! It makes web design simple because you can just drag& drop your files into place without having any technical knowledge or skills required at all (aside from knowing how use Photoshop).
You don't have access to FTP which means if something goes wrong with my website there isn’t much help available other than contacting customer service who are not always very helpful in solving issues quickly so they tend towards giving me advice rather then solutions - this leads them down paths where we need more time & effort but less resolution meaning even though i'm paying monthly subscription fees its still costing us money by taking longer before resolving our problems!! We've had little downtime due too server crashes etc..
