"Think about it logically, are you really likely to take a call and maintain an IM session at the same time?"
Yes. I've done this many a time. I'll be chatting to the office on Skype IM, a phone call will come in, I'll take the call, and then GO BACK to my IM conversation without missing anything.
This is why Windows Mobile is still superior, in my opinion. Bang on about the interface as much as you like, it still works. And you're not restricted in the kind of apps you can have, where you can get them or when you're allowed to bloody run them. If I want to open a web browser, IM session and a Word document (not that I like to use Word - OOo haven't made it to mobile yet), and then take a phone call, I ruddy well can. No worries, no bother, no fuss.
Windows Mobile might not have the most inspired interface, but people bang on and on and on about it, when in fact the only real thing they've got against it is that it's a plain old boring start menu, and it's not shiny, flash, or animated. Know what? I just don't care. I really don't. The start menu works on XP Pro for me, it works under KDE on Debian/Kubuntu for me, and it works on my mobile too.
Given the choice between shiny and useful, I'll take useful every time.
Now if you'll excuse me, I have to tune my sax/guitar using the app I installed on my Athena.
