It really, really depends what you do, pal. Linux is good for C-coders (love that term). But if you use your computer for other work, you're fried in any case equally.
Really? I've been a Linux only user since '98 and I can do everything I want with Linux, faster and better than any Amiga Like OS, Windows or MacOS.
Getting back on topic:
Can I ask some really annoying questions that probably get asked all the time.
1) How viable is Amiga os4.1 to use as a main machine?
2) I read somewhere that Firefox is available for Amiga os4.1, is this correct?
3) Does this handle flash as well?
Thank you in advance
1: You're going to miss your 'buntu box.
2: Nope, and it's going to take a while, people are still waiting for other ports like Blender. OWB is a good alternative though.
3: Not in a way you would like.
Why not try E-UAE (it's in the repo's) or AROS first? There's also
MorphOS, IMHO a much better choise.
All the Amiga flavors are fun as a hobby OS, nothing more nothing less.
