Worth installing Mountain Lion on late 2008 MBP?

I know there have been some reports of battery life issues etc. I'm just wondering if people have experience with MBP performance on late 2008 macbook pros. Wondering what the chances of it improving/degrading performance of my machine are..

I don't have experience with 2008 macs but my 2009 macbook pro is running great on mountain lion. I haven't had any issues with decreased battery life. It should be about the same for your late 2008 since mine is a late 2009. I think the issues people are having have to do with mountain lion being new and needing some updates/tweaks.

ML returned my mid 2007 MBP to Snow Leopard-like performance. I would recommend either SL or ML for older Macs. Lion just wasn't fully baked. YMMV.

To me not much of performance….

I'm running it on a late 2008 MacBook Pro (4GB/2.53GHz). I don't notice any difference in performance from Lion. I think it runs better. Might use a little more memory.

Note that I did a clean install. That has made a difference for a lot of people, but not everyone.

ML is smooth as butter on my Late 2008 MBP (2.4, 4G). No problems at all.

Just do it!

Penryn 2008 Macbook Pro and ML is a very nice and well done OS.
I do think it runs a little warmer overall, especially if you have a lot of Safari tabs open. Google Chrome seems to run cooler.

YMMV

no battery drain on 2008 MBP ? for me thats the biggest show stopper.

In my case, the performance was a bit improved and battery life is about the same (maybe a bit better)
