I was always a fan of the Apple Cinema displays. Picture density was fantastic the units themselves were solid and of high quality. I expect the thunderbolt displays are the same… they are just a little on the pricey side considering I just bought two 24″ Acer screens for $180 AUD each. Maybe if I get the new macbook at the end of the year.
The new thunderbolt displays comes with docking capabilities for new generation macbooks allowing users to recharge their battery when connected to the display as well as 3 x USB 2.0 ports and a firewire 800 port. Furthermore a gigabit ethernet adapter is also installed to complete the entire docking environment.
Units are available on the apple store now for a cracking $999 US.
