I am very strong with iOS but a newbie with OS / X.
how bad is the performance hit on the new Base 1.1 / 256 and is the security worth it to enable it?
I currently have a mid 2010 iMac 21.5 that I'm not using it..
thoughts?

well, mine isn't delivered yet (tomorrow), but i won't be using filevault.
first encryption does affect performance, disk speed or cpu, no matter how small (which you probably won't feel in real world application), there is affect.
and i think on this specific mac, login password + firmware password will do just fine. as to my understanding, file vault is to protect your hard drive, especially when it pulled out of a computer. in this event you won't need a login or firmware password to access the file on the hard drive, so you will need file vault. but for his specific mac, the hard drive cannot be pulled from logic board, which means you will always be protected by either firmware or log-in password.

Why not? Can't someone theoretically still take it apart if they weren't worried about damaging the other components?
Without file vault on, if I stole your Macbook, it seems I'd be able to boot into recovery and run terminal, and mount your file system and get whatever I want.

the rectangle on the upper left corner is the ssd. i doubt you can still read the data once it's pulled off the logic board.
btw, what's in your computer that others want so badly?
i mean, for most of us, encryption is just to protect some 'private' files, like photos, contacts, emails, not 'classified' file, right? it's not worth the time and money just to decrypt you family albums lol
well, if you do have like million dollar secrets in your computer, you don't need me to tell you to encrypt those files right?
I don't use or have ever used FireVault. I was just wondering if someone could take the SSD out and use it that way.
Realistically enabling File Vault will have no tangible effect on performance, outside of synthetic benchmarks.
Q-6
So what are the downsides to having it on? Do you? Other than losing your data if you forget the password.

well, mine locked up on the filevault yes/no question (i chose no) so i had to force-restart. now filevault is greyed out...
There are ways around the EFI password, you can find different methods via Google. It's best to use EFI Password + FileVault. FV won't have any noticeable performance hit.
I don't know about anyone else, but my tax records are on my laptop and that's enough to concern me for a lost laptop. Having someone steal your identity is a nightmare worth guarding against.

i use on my macbook pro, but probably not planning to use it on rmb. it's slightly inconvenient when you want to wipe the hard drive and reinstall system with file vault enabled.
and i won't have any sensitive info on this computer, that is the biggest reason lol.
How is it inconvenient? I'm actually thinking about using FV on the rMB when it arrives since everyone is saying there's no performance hit.
when your computer is lost, say someone steel it, they most likely are just gonna sell it for money, not interested in your data. and they will probably not open it up, tear down, and see what's inside your computer, they don't know whether its your contract, tax records, or just porn on your computer. plus, you can always lock&erase your computer remotely
btw, is it really a good idea to bring all your tax records with you all the time?
They would need to crack the EFI password AND put the laptop on the Internet for you to remotely wipe it. If I stole a laptop I would never put it online. Granted most thieves are as you say, looking to make a buck off the device itself. But not all are and identity thieves can be very intelligent.
It was just tax season so I did have that data. However even without taxes there is typically enough info in a laptop to steal the owners ID. Many people store stuff like CC numbers and other details in text files, calendar entries and other things for pulling up.
I see this all the time working in IT. So I take extra precautions with my own laptop and I always advise others to do the same. But I won't push it further. To each their own.
