So this distro is like a beefed up version of kali with a friendly to use user interface styled after Windows. It's basically a x86 Ubuntu 12.04.4LTS / Kali Hybrid. Solak comes with
Kali tools XFCE 4.10 Compiz / Emerald
A number of custom tools and open source software.
From what i've read it's pretty good but if you have any experience with it i'd be happy to hear about it. I'm currently downloading the ISO so that i can give it a spin in VMware.
This distro is pretty sweet guys besides the security tools what i also like is the amount of media applications it comes with such as gimp, a couple things are a little outdated but there's the possibilty to update. I'd recommend this distro if you want a pentesting environment with features that also make it useful for more every day applications. It looks very slick as well, i was planning on posting a couple screenshots but since i found a demo video on youtube i'll post it here for you to check out, it does the distro more justice than a couple of screenshots anyway.
All in all it's good to have if you want to run a Linux environment primarily. But since i use Windows on my main rig, i'm currently set as far as media applications go and i will be installing Kali 2.0 as VM as soon as it comes out for the latest and greatest capabilities as far as penetration testing is concerned.
