Complaints started mounting against the Transformer Prime's GPS capabilities soon after its launch. Users said — and our own tests confirmed — that the tablet was slow to obtain a positioning lock from its GPS unit. Asus recognized the problem and removed all mention of GPS capabilities from its marketing materials, and it offered several firmware updates to help solve the problem. They didn't work, however, and a teardown of the tablet revealed that poor placement of the GPS chip was affecting performance. Asus has since opened up registrations to owners that will see the company ship free GPS dongles to customers in a program that will end come July 31st, 2012.
