I am an X5000 owner. Also owned the X1K in the day but sold that and then missed running AmigaOS so much when the X5K came out, I did the deed again.
They are fun. Mind you things we take for granted like easy and fast web browsing that just works on popular websites and watching videos within the browser with ease, is just not up to par as what you will find on Windows or Mac or Linux boxes.
So if you come into this as you want to learn Amiga OS and tinker and take updates as they come, months or years later after we on Mac or Windows do with ease, then the experience will be fun.
I enjoy IRC chat so use my X5K mostly daily, chat on IRC, basic web surfing, watch some lower rez movies, listen to a little music... all fun for me with Amiga.
Real work for business I do on linux or Mac as it is very internet driven and just works on my linux and Macs where with Odyssey in Amiga OS, not so much.
