The first one (Jumeirah) is _very_ successful, and commands some of the highest house prices in Dubai.
It is on the back of this success construction of 2 additional Palms were started before 2006.
Palm Jebal Ali went bankrupt before any house construction began originally, but after construction of the island, and has been empty for quite some time (but not eroding).
Development recently began and the first villas have been sold.
Palm Deira went banktrupt before the palm part of the project was constructed and has been renamed to Deira Islands. There are some development there, but it isn't a destination anyone seems to talk about.
The scale of the 3 palms are miniscule compared to the wall in Saudi
