Still getting the Xoom on launch day. Truly, I still don't see any competitors. Google chose the Motorola Xoom as the device they were going to use when creating Honeycomb. This carries the same principal as their Nexus devices, where they build (or revise) an OS around a specific piece of hardware.
HP TouchPad - I really dislike the 4:3 screen ratio, lower resolution, lack of HDMI, and lack of GPS. At $699, I can easily justify an extra $100 for the Xoom.
Samsung Galaxy Tab 10.1 - Again with the lack of HDMI, plus this lacks USB. Not a fan of propietary ports either. I do like the design on the back the tablet. I truly think if they planned to beat the price of the Xoom, they would have announced the price when they announced the product. How else would they plan to stop people from buying the Xoom in 10 days?
Toshiba Tablet - I do think this looks like a worthy competitor, but who knows when and how much? Spring could mean anywhere from April-June. I personally can't stand when tablets default to portrait, and all of the ports on the side conclude that the Toshiba will dock in portrait. I've actually always thought this was the iPad's biggest failure, other than the iPod Touch OS of course.
LG G-Slate - Still don't know a price, but I think they are going to milk the 3D capability as a way to charge more. We're already seeing price in Germany, which converts to roughly $1,075US (pre-VAT). Even if the US got it for 30% below Germany, you're still looking at about $945. Plus, it's on T-Mobile. (edit: not that t-mobile is bad, but they're not my carrier)
Asus - I just don't know about the Transformer or Slider. They look fine, but most of the price ranges given at CES were going to put it close to Xoom pricing territory anyway. Neither are really expected to launch before April/May.
Notion Ink/Viewsonic/Huawei/Archos/Vizio - None are truly competitors to the Xoom. They all fall short in resolution, build quality (per plenty of hands-on testimony from tech sites), Android Market out of the box, etc. All, or at least most, are claiming to make Honeycomb available, but we've obviously heard that before. Plus, I don't believe any of these companies have confirmed that it would be vanilla Honeycomb.
