I wouldn't worry much about it. You'll not be able to buy overpriced music & video from Sony, and you'll loose the artifical Bravia colour "enhancement"
I wiped my TA partition 9 months ago and I haven't missed it at all.
Phone : Nexus 4 (16GB) with PARANOIDANDROID 4.1 ROM & FRANCO Kernel
Tablet : Xperia Tablet Z (311, 16GB WiFi only), back to Sony (KK 4.4.2) ROM for a try!
