This tablet comparison led me to buy the asus slider cause I didn't want to wait for the expensive Samsung Sliding PC. However the Asus Slider still can not be rooted.
The pros of the Xoom are 1) it can be rooted fairly easily 2) it has better battery life. The pros of the slider are that it (once it can be rooted) has the potential to be a real actual 405$ production computer because it has a keyboard, which makes it one step up from a netbook because it's lighter and less embarrassing to turn on on the train and then it can double as a tablet or production computer.
If you want root now and only want a tablet device to play games on and check email, go with the xoom. If you can wait for the ability to root it and want a $450 real work production computer which can double as a gaming email tablet, go with the slider.
