Hi there! Welcome to EF! There are actually a couple of posts on this already (here are a few examples
), so luckily you don't have to wait for an answer. ^_^
I've just started a new discussion with tips for posting new discussions (inception?) on EF's forums here
, and I think that you'll find it very helpful so that you can avoid posting a repeat thread in the future!
Personally, the only one that I own is an Xbox 360 - most of my gaming is PC. I have a few handheld devices as well, but I'm definitely not the owner of an impressive collection. Perhaps one day, if I have a lot of extra money lying around. =)
