So, as my title says, I bought SL the day it came out, but its still sitting on my desk, b/c I keep hearing stories from my friends on this board that SL is Apple's "vista" and it breaks everything and its just horrible. One of my friends couldn't use CS4, a bunch of them tell me MS 08 is mad slow, and for one of them Airport is broken. So I have time to kill this weekend, so do you guys think its finally "safe" to take the plunge and upgrade? I use multiclutch HEAVILY in Safari, so do you think this will be a problem for me to adjust to? I dont mind changing to 32-bit on Safari, but it will suck if it impacts speed by a ton?! So can you guys give me some good reasons to upgrade? I'm an Engineering college student, so I basically just use programming, matlab, a LOT of HD movie watching programs Like I watch A LOT of HD stuff, while I have like MATLAB open and Safari with 6 tabs open and like excel and word, haha. I also hate slow downs! I have a 2.4ghz, 2gb ram, 250 hd, unibody macbook pro from october 08 Thanks guys!!
