I went with the Toshiba Thrive and couldn't be happier. It's fast, responsive, and the Honeycomb OS is very, very slick. I can see a lot of potential in the OS and am looking forward to Ice Cream Sandwich (the next update that will integrate phone and tablet operating systems into one) later this year.

PROS
* Stable - I never experienced the sleep issue at all, but installed the fix yesterday anyway, since it offered some additional performance improvements. No issues out of the performance at all. Everything is fast and responsive. A joy to use.
* Responsive - Honeycomb OS is very fast, clean, and customizable. Very intuitive to use (at least for me). Adding widgets, etc. is fun and easy to layout.
* Video/graphics - Videos look great in all formats, but really snap in HD. All the graphics look great, and the text in the Kindle App looks amazing. Visually stunning. Everyone that has seen it has been impressed.
* Customization - You can set up the five screens any way you want. Widgets are wonderful things! Also plugged it into my laptop and it loaded up without any problems, allowing me to copy some pictures, etc. quickly.
* Multi-task management - The third button along the bottom left allows you to easily switch from application to application quickly. It's amazing how quickly you can get to something once you get used to using that button!
* Size - to me, this is a pro, because you feel like you're holding something and it's very easy to hold on to. You don't get the sense it's going to slip out of your hands, like you sometimes do with the iPad2. It doesn't feel cheap or cheesy, but very solid.
* Battery life - I've read some mixed reviews on this, but I get a good 7-8 hours of serious use out of it before it gets below 20%. Over nights, when sleeping, it uses 2%-4% battery life. And it does charge fast, they aren't kidding about that!

CONS
* The charger - Not a big deal, true, but it's a small laptop power supply, which I just find annoying to have to lug around. They should have a simple adapter you can use with the provided mini-USB to USB cable.
* Sound - Not really a big issue (and I may be missing something), but even with the volume all the way up on the device, it still sounds a little low to me using headphones. Maybe just a preference here, but I thought I should mention it. It does sound much better without the headphones on, though, but can be a little clinky and suffer from reverb on heavier tracks of music.
* Storage - not really a "con", but more of a heads-up. You won't have the full storage amount available to use. For example, if you buy the 8 GB version, you won't have 8 GB of storage to use. Honeycomb and other things (drivers, etc) take up part of that amount. Same with the 16 and 32 GB versions. Not a big deal, but I know some people are wondering why they only have 5 GB free when they bought the 8 GB version, for example.

OVERALL
A wonderful tablet, performs great, looks great, and has impressed a couple of co-workers enough that they are going to buy one. The full USB port was the big selling point for both. This tablet has been everything I'd hoped for and more. I would recommend it to anyone who is looking for a tablet. This is a great first step into the tablet pool by Toshiba, I must say. If you're wondering if this tablet will do what you want, I'm pretty sure it will :)

I give the Thrive 5 Stars.

NOTES
* There were a couple of image/OS updates ready to be installed right out of the box using Toshiba's SERVICE STATION app. I recommend immediately installing those updates before you do anything else. As with any new laptop, PC, phone, or tab, you should update it first before jumping into other apps, etc.
* I use ADVANCED TASK MANAGER to kill open apps that don't come with a native procedure for closing them. It integrates into Honeycomb very nicely, and all you need to do is tap the icon along the bottom right of the screen to open it from anywhere. Very slick and easy.
* I recommend that after updating the Operating System and Tablet image through the SERVICE STATION app, you set the LOCK SCREEN PIN (founds in SETTINGS >> LOCATION & SECURITY >> LOCK SCREEN). Also fill out the owner information (it will appear on the lock screen with the keypad). You can never be too careful, and if you do lose it, at least when someone tries to activate it, you'll have it PIN protected with your contact info right there for them to see.

Thanks for reading. I hope this was helpful.

What I wanted
I was looking for a tablet pc for three main things - surf the web, serve as an e-reader and that had a real USB port that I could use to download and backup photos from my old digital SLR camera. Note the camera uses compact flash memory, not micro SD, so I can't use that to transfer the photos.I had previously bought and returned the eLocity A7 Android tablet because I couldn't get it to do the things I wanted.Don't like the whole concept of the controlled Apple world plus the IPAD lacks a real USB port though you can get an adapter.

Overall
I've been very happy with the Thrive.The screen looks great and the touch features work smoothly.It's a little heavier than some others, but I generally rest it on my lap so that's not an issue.Haven't had the dreaded not waking from sleep issue.The file manager that's included is straightforward and easy to use.I was able plug in my camera and copy files with no problems.Also, I added 32 GB more memory using a standard card, which can be swapped out if necessary.There aren't a huge number of apps yet, but they include enough to make it immediately useful and the number is growing.

Minor annoyances
As others have mentioned, the on/off button is inconvenient to find, especially in low light.
You can't close apps without turning off the tablet - though this may be a function of Honeycomb.
You can't delete the included programs, but really they don't take up much space.

It doesn't come with any directions except a small startup pamphlet.Typical, I know, but would it hurt them to include a pdf on the tablet with more details?FYI, here is a link to an Android 3 manual [...]

Apps
Comes with a fine file manager and browser.There is also a gallery program to review photos and a bunch of solitaire type games.The maps app is really great - it works with the gps system so you don't have to be in wifi range to use it.It also can be used to get directions or look for restaurants etc near you.

I have so far downloaded Kindle and Aldiko book readers which both work fine.Also got a free photoshop lite program to do simple photo editing.And I'm afraid I'm already addicted to Crazy Birds.

There is a list of optimized to Honeycomb programs here

Sadly, Netflix doesn't yet work, but hopefully will soon.

Bottom Line
I've had the Thrive for a couple of weeks and it can already do all the things I was looking for and more.There are a few annoyances, but mostly I've enjoyed playing with it and plan to keep it.
