IGN's impressions:

Chris:
"The fact that the buttons are a little lower on the system than the current one means that you don't have to form as much of a claw to use the shoulder buttons. There's more distance from the bulk of your hand and your index fingers with the go, which should make it more comfortable in the long run. I hope that the fact that the buttons are flush up against the back of the screen portion doesn't mean that they'll get cramped that way, but so far so good. The shoulder buttons also feel more responsive than the current plasticy-feeling buttons."
"I like the size quite a bit. I never carry my PSP around unless I know that I'm going to use it simply because of its size, but that may change once I get a PSP go. The analog stick also felt a little more solid and smooth than the current one, but I'll hold my final judgment on that until I get more time with it."
"My two issues are with price and what you'll do with your current library of UMDs." (This was before the Good-will announcement - either way).
Scott:
"When I first saw the leaked images of the PSP go, I couldn't help but feel that the design was a step backwards for Sony."
"What's more, the physical dimensions of the device are hard to gauge from the press photos."
"Instead, when you get a glimpse at and feel of the PSP go as one of the product's target audience -- semi-adult and male -- the device is strikingly compact."
"Despite its incredibly compact design, however, the PSP go isn't too small for those same enlarged, semi-adult male hands. My fingers wrapped comfortably around the edges of the device and I didn't have to cramp or arch my fingers to get a good feel on the shoulder buttons."
"Outside of my concerns about the physical size of the device, another big worry of mine was the positioning of the thumbstick. Again, misled by the in-hand promotional pictures, the thumbstick appeared to be bit of a reach for a player's thumb, but in reality its within a comfortable range." Funny, I didn't think it was but I did think the Go was small from the get go so...
"In a perfect world, I would have liked to have seen some serious processing boosts, but I expect that the flash-based games will take a sharp performance boost anyways."
Greg:
"I'm all over the place on the PSP go. I think $250 is too much to charge for a platform that's been out for four years now, but I definitely think it looks sexy. I think the slide screen might make accessing the shoulder buttons hard, but I dig the compact size. I got to play the PSP go yesterday, but it was in a metal holder and anchored to a bar so the weight and feel of the unit in my hands was off. I felt like the nub was in a goofy place, but Roper played it without the holder and said he didn't have the same problem so I think that concern is mainly due to the holder."

Noteworthy Pros:
"the PSP Go has one of the nicest handheld screens on the market, if not quite up the iPhone 3G's."
"Despite its smaller size, the PSP Go is actually more comfortable to use than the older PSPs. The L and R shoulder buttons are oversized and squishy, given you a great grip on the device. The analog stick is logically placed (though the placement looks weird in photos, it works well), and the new directional pad is shallower and clickier but works well."
They also mention the things Sony is doing besides the hardware itself to help the PSP Go and PSP overall, which was a point I was trying to make.
Noteworthy Cons:
They see no 2nd analog as one, I still disagree 110%. They suggest lock on controls for the 51+ million PSP owners without 2nd analog. What about online games?
No touch screen.
Conclusions:
"Overall, the PSP Go will re-energize the PSP ecosystem and get more developers and publishers interested in the device." Big point I agree with.
"It's not a perfect showing, though. By eschewing a second analog stick or touchscreen, Sony is stubbornly sticking to the PSP's original vision - an oversight that may cost them in the years to come."
" With a touchscreen and an analog stick, the PSP Go could have cruised along steadily for years to come and rendered a PSP2 unnecessary altogether." Gotta disagree with this a lot, Apple will keep upgrading their lineup.
