Check out Fake Steve's take on Mossberg's review
"* adds multiple steps to common functions that are easy to perform on a regular phone.
* runs on EDGE, which is pokey, and the can't be upgraded to run on faster networks.
* does well on Wi-Fi, but this "doesn't fully make up for the lack of a fast cellular data capability."
* won't work with a lot of iPod accessories.
* has no overall search.
* has no quick way to move up and down on pages.
* has no way to cut, copy or paste text.
* can read Excel, Word and PDF documents, but can't edit or save them.
* can make phone calls but in many ways it's a pain in the ass, even more so than with other smart phones.
* boasts voice quality that's "good but not great."
* has no way to get your contact list from your old phone.
* can't turn contact groups into email distribution lists.
* has some third-party apps, "but the few we tried weren't impressive."
* has no instant messaging.
* can't record video with its camera, and has 2-megapixel resolution.
* has no support for Flash, so can't view stuff on some Web sites.
* can't turn your iPod songs into ringtones.
* has no games.
* can't access iTunes Music Store directly.
* costs twice as much as its competitors.
* isn't for the "average person" who just wants a cheap phone for making calls and texting.
* probably isn't for corporate types either.
Conclusion? "A beautiful and breakthrough handheld computer."
Of these, I think the first about efficiency of input, the speed/quality of the network, the one about editing Word files (which the previous point about clipboard functions is really part of the same point), the lack of iPod games, and the lack of OTA syncing and iTunes purchasing are legit problems that Mossberg seems to say "oh, but it's worth it anyway." Most of the others are either sub-points, are agiven, or are a bit inane IMO.

NY Times Review by David Pogue
Highlights:
"Making a call, though, can take as many as six steps... Call quality is only average, and depends on the strength of your AT&T signal.
"E-mail is fantastic...
"The Web browser, though, is the real dazzler...
"...In practice, you’ll probably wind up recharging about every other day.
"There’s no memory-card slot, no chat program, no voice dialing...
"The two-megapixel camera takes great photos, provided the subject is motionless and well lighted . But it can’t capture video. And you can’t send picture messages (called MMS) to other cellphones.
[regarding keyboard]"...once you stop stressing about each individual letter and just plow ahead, speed and accuracy pick up considerably.
"Even so, text entry is not the iPhone’s strong suit. The BlackBerry won’t be going away anytime soon.
"...When you’re in a Wi-Fi hot spot, going online is fast and satisfying.
"But otherwise, you have to use AT&T’s ancient EDGE cellular network, which is excruciatingly slow... [He then adds some truly ridiculous, possibly suspect times for page loads on EDGE]
"...I encountered a couple of tiny bugs and one freeze.
"In other words, maybe all the iPhone hype isn’t hype at all..."
