When I first bought my iPad, I thought it would be a household device, but by the time I had my Twitter push notifications and my Angry Birds high scores up and running, it was pretty clear who it belonged to.

So I was interested to see that personalized news reader app Zite today launched a new version that allows users to have multiple profiles.

CNN-owned Zite justified its new “Sybil” features with a survey in which one third of iPad-owning respondents said they shared their devices. (The research was conducted as a poll on Ask Your Target Market with 330 participants.)

Support for multiple users seems particularly helpful for an app like Zite, which learns over time what kind of stories each user is likely to enjoy. Of course it might be even better if Apple offered a multiple user feature on the iPad as it does on other devices.

Various developers have released and mocked up multi-user tools for the iPad. Berg London designer Matt Jones wrote last year, “The individual nature of the UI and user-model of the iPad seems so at odds to me with its form-factor, the share-ability of its screen technology and its emergent context of use.”

Also, its price!

Hopefully, we will find out this morning the 411 on the Microsoft’s (MSFT) latest parry in its attempted takeover of Yahoo (YHOO).

But, before that, let me get this straight: Microsoft CEO Steve Ballmer now wants to go hostile on Yahoo with a proxy fight.

Because earlier this week, he sent smoke signals that he was considering raising the price of his takeover bid for Yahoo.

And just before that, Ballmer was going to walk away from the deal. Except, before that when he was ready to lower his offer.

But don’t forget the friendly path Ballmer was also promising. Even though his initial unsolicited offer started off back in February as, well, hostile.

Calling Dr. Phil!

Perhaps the wacky TV shrink can merge together Ballmer’s multiple personalities into one, much the same way he tried to mend Britney Spears.

OK, that did not go so well. But it couldn’t be worse than the confusion of intentions from Microsoft here, including the latest one reported by The Wall Street Journal’s crack team today that Ballmer had now selected hostile as his choice.

Here is Ballmer’s money quote, the likes of which a Zen master could not interpret: “With the right circumstances it’ll happen. Without the right circumstances it won’t happen.”

What? That just about covers every option possible and then some. This may even require an Oprah intervention.

Here’s BoomTown advice, which we reiterate from yesterday’s post: Offer $33 to $35 a share as a best and final, take-it-or-leave-it offer. Set a 48-hour deadline for Yahoo to enter negotiations. After that, initiate a proxy fight.

This says a lot of things. It says Microsoft is generous (and will even bid against itself). It says it has had it waiting for Yahoo to dangle Google (GOOG) or AOL (TWX) as alternatives. It says definitively that Microsoft wants Yahoo and will fight for it.

Most importantly, it says enough is enough.

And while this may seem like it says a lot of things, it doesn’t seem–as so much of what Ballmer has been saying so far says–like the rant of someone in need of help.

Because, as it stands for Ballmer, that’s what it sounds like right now.
