Since I use a lot of PDF stuff, the default is my current weapon of choice, but I've used Wicknix' packages to add GCC and Python to the mix for my own tinkering pleasure. I've also applied the 'increase the concurrent tasks' hack, and some other patches and tweaks... but really, I only need to browse, write, do simple calcs, email, access PDFs, and tinker with C (and maybe python...)
I'd *like* to use 3MX, but it would need the PDF reader, and to lose some bloat. I think the form of 1.1 RC was more to my taste, since it had a minimal overhead, while adding significantly to the tool set, andhad a clean look and feel. While RC3.x is excellent, it seems a little 'busy', and overloads the system at times. I also like Pidgin, the lack of which put me off RC3 somewhat...
I'm looking forward to trying the 'Classic' Remix...
None of the above should be regarded as an unconstructive criticism of Wicknix's sterling work, just a view into how I found the different options, and how I work with the wee beastie...
