I'm here to ask you guys for a bit of advice.
I bought a seconhand mid 2010 Macbook Pro (2.66 Ghz i7) and Lion had already been installed by the previous owner. I had heard a few bad things about it but honestly at that point I didn't care that much as it as a new Operating System and I never though it would be like this, especially coming from Apple. As soon as I first charged it I realized the battery life was nowhere where it should be, at a maximum of 3 and a half hours of light use. And the fan noise is impossible. Right now it's silent, but it gets to the point where I only have chrome and Itunes open and it sounds like I have a truck in my room. I just put it to sleep because I can't handle it.
This was my first mac so I'm unsure if I've gotten too used to the Lion features (multi-touch trackpad is the only one I remember now, but, again, this i my first mac so I don't know if I've gotten used to something that is only available on Lion) or if it too risky to downgrade, as I will soon be outdated by two OS's with the release of Mountain Lion next June.
I'm a Graphic Designer so I use Adobe programs quite a lot (mainly Indesign, Illutrator and Photoshop) and other things like Office, Itunes, Skype, nothing much really... Battery life is important because I will be travelling quite a while and would really appreciate having the 7 hours I should be having (or at least 4 using Adobe applications). And no fan noise, for the love of god.
However one of the main things I'm afraid of is going back to Snow Leopard to realize that the problem is actually my battery and not the OS, as some people on here have had problems with the battery itself as opposed to being a Lion thing (Lion probably helped, but even so), because when I got my Macbook Lion had already been installed so I have now idea of how was its performance like with SL. Should I take the risk? If ML proves to be fine would I have to buy again Lion and then ML?
Thanks in advance.
