so you guys mean i definitely get the Lion!
Not at all, at least that is not what I think is the general intent.
1) We have no idea what hardware you have
2) We also don't know what software you are running (and there are potential compatibilty issues with older software)
3) We also don't know what you hope to gain by the upgrade
I think Vansmith's post was simply to encourage you to do some research because there is a lot of information out there and many threads related to this topic on this site (we have a search tool that works quite well).
To be absolutely honest I originally ignored your post and didn't bother to reply because of the lack of information from you and the apparence that you had done zero research on your own.
We can (and are glad to) help, but we can't decide for you--if for no other reason that we don't know enough about you and your situation.
