Here's a grab of my current desktop, showing the Ubuntu Lush theme, the new Cardapio menu applet, and the use of Ice web-apps:
The drop-down menu at the top-left is Cardapio, and everything is in there; it's like a KDE or Mint Menu; then there are dedicated Ice-made web-apps for Facebook, Gmail, Yahoo mail, this blog, and my 4shared page. At the top right pidgin is inside the envelope and there's also a green button (not shown in the grab) that says that I'm available (online) through Mxit. For me, this is all very Mac OS 7-9, my favourite desktop era. This is all Ubuntu/Peppermint though, not Mac.
Lush is available through synaptic (in a collection of gnome-2 themes); Ice is available by adding the following ppa and then checking Ice in synaptic:
sudo add-apt-repository ppa:kendalltweaver/peppermint
Cardapio also needs the ppa added:
sudo add-apt-repository ppa:cardapio-team/unstable
sudo apt-get update
sudo apt-get install cardapio
