[Eee Pad Transformer General] coachclass:
I just got my hands on a Toshiba Thrive from BB, so thought I'd share initial impression. I'm not going to rehash the specs, since everyone's smart enough to read the specs and figure things out for themselves.

Cons:

-the plastic cover that covers the dock connector isn't tethered. But to be fair, neither the Transformer, Tab 10.1, or iPad has a cover over the dock/charge port.

-huge AC adapter for charging. It's about half the size of my laptop power block. I didn't see that in the reviews. But, see associated Pro below related to power port.

-keyboard lag when a few apps opened (not really a con relative to other Android tablets since they all have the same problem, at least the Transformer an Samsung that I've tested do)

-the infamous youtube.com/my_speed test which may or may not mean anything at all: about the same performance as Samsung, and much better than the Transformer. 30fps at 720p, few dropped frames. Still saids software video rendering like all the Android tablets. However, stock browser embedded youtube videos are still jumpy. Again, not a con since it's Android problem, and other droid tablets have this the same issue. Flash will probably give way to HTML 5, so over time is it a biggy?

-I don't know if heat matters...but the Transformer didn't really have any "hot spots" when you let it run for a while. The Samsung did, and so does the Thrive. I haven't worn in the battery yet, so I can't say anything about battery life. The Samsung Tab 10.1 I test drove had the best battery life out of the box. The Thrive and Transformer seem about the same, but I've never really worn in the battery on either.

-the screen viewing angle isn't as good as the transformer or the galaxy tab. I kind of think the Galaxy tab's viewing angle is about as good as the Transformer, which other people dispute. So take my judgement with a grain of salt.

-certain games (angry birds) default to landscape mode. But it forces you to hold the Thrive in landscape upside down. Not a big deal, except the volume button are reverse from what you would expect them to be (left is louder, right is quieter).

-volume buttons aren't very tactile. Can't really feel them. It's squished with with the power button and the orientation lock button. Bad ergonomics.

Pro:

-separate charge port (round AC adapter type) and data dock port. I like that. Less wear/tear on the data port. The round charge ports are built to be frequently used. The power block outputs 19VDC, 1.58A. Not sure how easy it is to find a spare charger.

-grippy back makes it more comfortable to hold. I would say it's easier to hold than the slightly lighter Transformer because of the grippy back, but like the Transformer it's still too heavy to hold one handed. Side note: I wish there was a weight distribution rating on these tablets. Weight distribution matters. It feels like Thrive is slight better distributed (weight in the center).

-much better speaker than Transformer without speaker fix.

---------------------

So, maybe because this is my third tablet, but I'm much less impressed with the Thrive than the Transfomer and Tab 10.1. I haven't mentioned any of the pros like full size USB and SD card simply because they're obvious. You don't need me to tell you about them. Also, Toshiba didn't include very many freebies in the stock OS. The programs (games) that are included are not paid for - you need to sign up to play. So, they're kind of useless.

For those who don't like the backplate flex on the Transformer: since the Thrive has removable backplates, it also flexes. But not along the rim like the Transformer.

Will update when I get more experience with it.
