Me and my brother won a Blackberry Playbook and though you can't even search in pdfs and it demands use of cifs. I'm a little impressed with the spec, I'd have no idea if I didn't have one.
Apparently it has compiler and linker protections, Propolice, PIE, full RELRO, ASLR and what led me to find out, PF. I believe henning mentioned somewhere that Apple were adopting an out of date PF but I didn't know other companies were. Does anyone know of any others? -- Kc
