I totally agree with the cat eye as Logo; simple and it has a good vibe with credibility.
With AROS, what's to complain about? While it may not yet host a usable browser and have all the features & apps we take for granted in 2007, neither does any other Amiga/Amiga-like OS.
If you like AmigaOS and want a modern Amiga-like OS with real potential, (free of the IP holders' political wrangling), running on a variety of cheap old->new hardware, and it's free!
Keep up the good work fellas, well done!
