- Asus Transformer Prime
This is currently my favorite, for a few reasons: Tegra 3 quad core processor (that's just plane cool); Its designed with a docking station in mind, making it perfect for using for work; Sleek thin design; light weight; available with up to 64 GB. It is on the pricey side though.
- Toshiba Thrive
I must admit, I know very little about this one. Unlike the others, I have not heard much hype around it. From what I've read thus far, pros include: full size SD slot; full USB support; Full HDMI support. Cons: Bulkier and heavier than its opponents.
- Motorola XOOM
This one has been available for some time, which can be both good and bad. Its problems should be known, and understood by now, but its lost some of the sex appeal of the new product.
- Samsung Galaxy Tab
The Galaxy tab line has also been on the market for a while. It does have some added appeal to me because my phone is also from samsung, so the rooting processes, and available ROM's will be more familiar to me.
- Sony Tablet S
Like the Toshiba, I have heard less hype about this tablet. Its feature set also seems similar to the toshiba. I must admit here, I may be a bit biased against sony over some of their recent treatment of the hacker/maker community.
