I will never again buy a Nokia phone.
For Lumia it's an optional download, but then again the Lumia markets don't have to worry so much about big brother.
So, effective use of Xpress could be limited to articles (The Verge), magazines and mailbox use could be done through IE or through the mail app. The problem is limited on the Lumia phones but it is a bigger deal just on their S40 phones.
