What is really needed is an Amiga laptop ...

but what means the letters UAE?

One of the really big questions, that not even the UAE gurus knows the answer to.

It seems to me that it has only had one official meaning: "The Unusable Amiga Emulator" which the first versions were called.
This was simply because the first release couldn't even boot. When it later booted, some creative soul named it "The Usable
Amiga Emulator".

Meanings I've found searching the web (excluding "The United Arab Emirates"):
The Useless Amiga Emulator (11 google hits)
The Usable Amiga Emulator (26 google hits)
The Unusable Amiga Emulator (103 google hits)
The Universal Amiga Emulator (114 google hits)
The Ultimate Amiga Emulator (351 google hits)
The Ubiquitous Amiga Emulator (435 google hits)
The UNIX Amiga Emulator (strongest, 714 hits)

Looks like "The UNIX Amiga Emulator" is the winner. FDict and Wikipedia support this meaning too. WinUAE would then be
"The Windows UNIX Amiga Emulator" which is pretty cool.

UAE might however be a recursive acronym. Asking what UAE stands for might be the same as asking what GNU stands for.
GNU means "GNU's Not Unix", UAE might just stand for "UAE Amiga Emulator". I think this might be the case, because the title
 on the UAE website is simply "UAE - The UAE Amiga Emulator". "UAE Amiga Emulator" gives 2660 google hits, "The UAE
Amiga Emulator" gives 642 hits.

On my lips, it will always be "The UNIX Amiga Emulator". Linux, linux, linux! :-)

I'm pretty sure the 'u' is for 'ultimate'. Wikipedia is written by anyone who has the initiative to click "edit this page", so unless someone corrects an error (or vandalism) it remains there. If it's important, wikipedia may not be the best source because I find things wrong there often. (Especially grammar'n'junk. )

Well, BBC has narrowed the Amiga down in this page - The Commodore Amiga.

This is what they write about UAE:

9 There is no general concensus as to what UAE stands for, except that we know it's an Amiga Emulator. Linux users claim it to be the Unix Amiga Emulator. The author says that during most of the program's development it didn't work, so he christened it the Unusable Amiga Emulator. Anyone who uses it for MS-DOS or Workbench systems says that it's the Universal Amiga Emulator.
