Bing vs Bing(beta)

[cleanup]

I notice that sometimes (depending on language selections etc) I am presented with either Bing or Bing(beta) results.

Why is this? and which result set is the important one.

As far as I can see the Bing(beta) results are better (more complete).

Even the home page picture is different between the Bing(beta) and bing.

Can anyone shed some light?
What version are you seeing Bing or Bing(beta)?

[inbound]

Bing is in Beta in countries such as the UK; Microsoft is still working on localised engines and will come out of beta (and do a big advertising campaign) in each country when they believe their product is right.

Bing is out of Beta in the US and Canada - so if you go to the .com (and do not have the country selection attribute set) then you should see no Beta sign, but go to the .co.uk (or [bing.com...] ) and you'll see the Beta.

You can see different countries by altering the cc like so (or try the local country code domain, but I don't know of Microsoft has EveryBing):

[bing.com...] (note the ninemsn at the very top right)
[bing.com...] (note Simpatico at the very top right)
etc... (try mx and others that have language differences and you'll see interesting stuff)
