I currently have 150 MB for my 9900 but am thinking about getting the Z10 due to the new $200 unlocked price.
I message/email a lot, browse here and there, and barely use 50 MB on my 9900, but I understand that the Z10 does not have BIS compression.
I would not stream audio/video on the go.
is it even worth upgrading? I love the physical keyboard but as my 9900 is 2.5 years old, it just isn't how it used to be.
