I like that they are constantly improving their product, which is great for us developers who use them every day. The interface can be difficult to navigate at times, but this has improved over time with new updates. It would also help if there were more tutorials available online or in books so we could learn how to do things without having to rely on other people as much. This helps me when working remotely because i don't have access to my coworkers all the time. We've been able to get our jobs done quicker than before since implementing Aptana Studio.
