@ Spearchucker Jones .... To assume....
"Advocate, contacts appear split because you have entries for one person from many places (LinkedIn, Twitter, Facebook, Windows Live and Exchange). You can link them to make them appear as a single entry. This is by design, and IMO an awesome feature"
I know all about this and for the majority of my contacts this is true however I have one friend in particular who has the same entry being displayed no less the 36 times in my phone book. Whilst he is present on FB, Twitter, G+, Live & Linkedin he does not have that many accounts. This is irksome and weird behaviour.
In addition, there is a limit to how many accounts you can link and you cannot link a live account to a live account.
I look forward to Mango, mainly for the IE9 improvements but I am no longer a developer and haven't been privvy/bothered looking too closely at what else mango brings.
Re timers - yes there are 3rd party apps for that but why isn't it part of the standard build?
Also, forgotten in my previous post - I hate bing, it is a rubbish search tool. Purely subjective but there you go.
