What is it you want to do with the PE? Allot of discussions here are about getting access to the 'Android Market' proper; where apps are more plentiful. However, not all Android apps will work with the PE or EE (10.1" model). There are many places to get apps and discussion here on which versions work.
As well as gaining access to Gapps (Google apps).
My advice
BEFORE deciding to do any changes is to get used to the PE. Read through the user manual and understand all the different functions.
And,
Welcome to the 'eDGe' of the world!
ps. Your PE is
red?
