OK so given Android phone increasingly popularity here's a list of key Android Apps taken from various threads here and elsewhere.

Would be interested to note any comments, v1/v1.5 compatibility, additions etc

[sadako] Can topic be changed to read "Essential Android Software for G1, Magic, Hero/G2 Touch" please?

[cj_eds]Would be nice to see this list formatted instead of a random list of names? See the iPhone and PC freeware threads for example. Especially as Android grows in popularity and more people can recommend apps and widgets. A bit more organised and we can maybe get a sticky for the thread too mods?
Feel free to sort out any you've previously added and feel free to change the headings I've made because there might be far better ones!

Been adding in this format:

Name

free/price

Description, inc weblink if not on Market

or in wiki formatting!

|| Name || free/price || Description, inc weblink if not on Market || 

IS IT POSSIBLE TO ADD THE DATE TO YOUR RECOMMENDATION? ITS AWKWARD KEEPING TRACK OF WHAT IS NEW AND WHAT HAS BEEN ON AWHILE. A DATE, OR AT LEAST NUMBERING ENTRIES WOULD MAKE NAVIGATION EASIER.
