Not impressed - its usable, but less than it used to be.
I find it enormously more bandwidth hungry - infinite scrolling just consumes the bandwidth. If you have an unlimited connection, then it may not matter much. For those of us on a modest monthly cap, its a big deal.
The terabyte limit is a bit of a joke. Taking into account the 300mb/month upload limit, it would take approximately 277 years to get up to a Tb. I'm eagerly awaiting those new anti-aging drugs ;-)
