In "The Metamorphosis," what things about Gregor have been changed and what seems to have remained the same?

Ironically, given the title of this story, it is possible
to argue that this story does not focus so much on the change in Gregor as in the way
that Gregor's state and condition has not changed much at all. Note the way that the
newly-transformed Gregor does not spend hardly any time debating or questioning his new
condition. He just continues to moan about his position in life and how he is exploited
through his work, and although he does not say this, exploited through his family, who
are dependent upon him. This indicates that his actual state has not actually changed
that much. He was treated like vermin before, and the only difference is that he has now
become what he has been treated like.

What has changed
though is the physical nature of his appearance. This of course makes mobility much more
tricky, as his attempts to get up show:

He therefore first tried to get his upper
portion out of the bed, and to do so he cautiously turned his head toward the side of
the mattress. This actually proved easy; and eventually, despite its breadth and weight,
his body bulk slowly followed the twisting of his head. But when his head was finally
looming over the edge of the bed, in teh free air, he was scared of advancing any
further in this manner; for if he ultimaely let himself plunge down like this, only an
outright miracle would prevent injury to his
head.

In addition to the
physical problems of negotiating movement with his new body, he finds that he is unable
to communicate with other humans, as the speech that he utters comes out as animal
sounds. Obviously, as well, the transformation and the way that his family treat him
mean that he is able to rest and stay in his room and not get out like he had to when he
was working so hard as a salesman.
