I would say the problem is is that you're probably using pirated software since that is a rather old version of Lion and one you should have only if you're a developer.I installed Lion build 11A390 developer preview 1 on my MacBook Pro 1,1.

I hate safari. plus, my disc drive won't burn on SL and it does on lion, my computer gets to 180* on SL and only gets to maybe 135* on lion. it's just more of an inconvenience to go back. :/
