Great thread so far, I do like the comparisons of 7" vs. 10" tablet screen size. We can all agree that we are huge Android fans here, so JerzieBarbie, I hope you are also posting this type of thread at Crackberry.com to see what those guys have to say. Definitely try out the Playbook first before buying the Xoom.
That being said,
I have a Nook Color. Love it. Absolutely brilliant. I am going to get a 10" HC tablet soon, and I was all set to get a Xoom. However, when I used it in the store I was surprised at how
heavy it felt while holding it. After about 30 minutes of holding it non-stop, pain started developing in my wrist. I am a little surprise that no one mention the weight factor in this discussion as it really starts to matter if you have to hold the device for a long time.
It's the reason I couldn't commit. It's too heavy. Whereas the Nook Color feels much more manageable for longer periods of time.
That's one of the Playbook's advantages. Maybe it's just me, but weight is the primary reason I am looking at
Samsung's Galaxy Tab 10.1. It's thinner, which is better for holding, it's lighter, and it's WiFi version is coming in less than 2 months (June 8th)!
If you can hold out, that's the device I think you should seriously consider. I know it's the one I am considering!
Hope this helps! (But I know it'll probably confuse you all over again!)
