I guess you mean that it doesn't look like Android or iOS. This can be changed easily through a theme. Conveniently you can download new themes from the theme settings screen, you don't need extra software nor you have to search in random places.
On the other hand, certain programs, like its text editor which can highlight code in almost every known computer language, does regular expression searches, support vi input mode etc, can't get much eye-pleasing. But you do get something you can actually work on.
I love the touch drived interface of tablets, but I don't think there is a reason to hide that a tablet device is a computer in different form and when you need it, it can perform as thus.
