The main disadvantage of integrated packages is that they are less powerful compared to stand alone applications. They typically have fewer features compared to their general purpose package counterparts.
Since all the applications within the package are loaded from a single launch, they will all be simultaneously loaded into the memory, even if the task being performed is simple and does not require a lot of computing power.
Despite their shortcomings, integrated packages are generally cheaper than separate programs. All the applications in an integrated software package usually have a similar graphic user interface, this makes switching between application seamless and simple.
