Walt Mossberg's take:

Bottom line: If you’re looking for a $100, high-end smartphone, or are a Windows Phone fan who has been waiting for better hardware, the Lumia 900 is worth considering. But the phone had just too many drawbacks in my tests to best its chief competitors.

Ranked by order of length. Of course, he couldn't know about <a href="http://www.guardian.co.uk/technology/2012/mar/15/ipad-3-review">our review</a>, which didn't launch until 7am, and weighs in around 3,230 words (pictures too!), thus making it third-largest.

"Unlike with, say, an iPad, it's unclear if the tradeoffs to the Chrome OS-based systems make a lot of sense for typical consumers. And unlike a typical netbook, you're losing out on a lot of valuable Windows-based functionality.<br />
"I just don't know what to make of it.<br />
There's certainly a lot of promise here, and if you're a big consumer of Google services--especially Gmail, Google Calendar, and Picasaweb (photo sharing)--Chrome OS may eventually make a lot of sense. I say "eventually" because Google will improve its services this summer to support offline usage, a key problem with the system today. And I say "may" because, let's face it, anyone can just run Chrome on a Windows-based netbook or notebook. Why limit yourself only to Chrome OS?"<br />
<br />
Amazing how many people review the Chromebook as though its prime audience was going to be consumers. It isn't.

"it took us a couple of days and a helpful hint from the chief designer of the PlayBook to find out that we could turn it on without the use of the power button. All the functions are there from the start, but RIM doesn’t detail them in any of the accompanying literature."<br />
<br />
But he makes house calls, right?

This is a chip shop fight of a review: short and brutal.
