The Xoom looks great but for the price it might be wise to wait a while as the tegra2 device will become more readily available.
Have purchased the Notion Ink Adam (
www.notionink.com) and the device works well. They had some hickups with the ordering process and delivery dates which were delayed a few times. With their new updates it works quite well however waiting the Honeycomb update which would then make it awesome.
The xoom has stock Android 3.0 so you can expect the same experience on other Tegra based devices as Nvidia has been working very closely with Motorola and now with other manufacuturers to accomadate Honeycomb on the tegra2 processor.
I have another 9.7" Android 2.2 wifi only device (
www.thetabletpc.co.za) which is excellent for home use especially for reading. Device is quite wuick and has 512MB RAM so decent for the price.
The Playbook looks good as well and from the videos on YouTube it looks quite decent.
I am not a fan of the smaller devices like the 7 inch unless it is just for reading eBooks.
Android market is growing and lots of good apps to look forward to. I think the apps will get better and more app makers will develope for iOS and Android concurrently rather than a delay for the Android app as was hte case in the past.
Wonder if people would consider the cheaper chinese based devices with Honeycomb. I am sure not everyone can afford the Xoom (Me included)
