Any issues upgrading a MacBookPro4,1 (Early 2008) to Lion? I have a MacBookPro4,1 (Early 2008) with the following specs:


Intel Core 2 Duo 2.5 GHz
4 GB RAM


I know that this model is supported by Lion but I'd like to know by people who has already performed the upgrade if:


they've noticed a performance degradation after the upgrade
if there are any other gotchas when upgrading
I upgraded my MacBook Pro 3,1 (late 2007) with 6GB RAM to Lion. There are no specific problems, but note that the trackpad cannot use multi-touch gestures. Also, the networking circuitry in my MacBook Pro does not support AirDrop, so I can't use that. I noticed inconsistent behavior with keyboard backlighting on my model with Lion, but since I have never seen the need for that feature, I just disabled it altogether.
