I bought a new imac last September, so it's not even a year old yet. I was wondering if it was worth upgrading to Lion or sticking with Snow Leopard? Also, what would the benefits be to upgrading to Lion?
Performance-wise, I think you’ll be fine as long as you’ve got at least 2GB of RAM in it. I have an iMac from 2009 at home and it’s been running Lion just fine.
As far as benefits to upgrading, see Apple’s page here to get an idea of what it’ll give you. If you ask me, it’s well worth the $30.
