Not wanting to nitpick, I'm sure millions of hotmail users are grateful that it's caught up with the pack, but it does leave me wondering:
Why would anybody want to turn off conversation view? There's a reason why Apple have made it standard in iOS4 and why you can (apparently? I've not used it first hand) use it in Hotmail too. There's basically no reason *not* to want conversation-threaded emails...
10GB emails? Geez I can see exchange admins everywhere loving that ... ? I thought 10MB was the general limit most companies have for email? Except, they're not actually being emailed are they, but just linked to your Skydrive :-/
Still, 25GB of online storage with Skydrive is generous of Microsoft. Google only offer ~8GB I think for Gmail?
Embedded YouTube, UPS tracking and easy Doc Editing is nice, but still just catch-up
