I have the keyboard dock and really like it. I did my little review on it on Saturday. Search and you should find it. Others also chimed in with their impressions. The portability factor is something you will need to judge for yourself. The back support for the iPad does not collapse, but depending on how you pack and the size if your bag this may not be an issue. I never measured it, but the back support actually is shorter than I expected. I also found it very sturdy and substantial so i would have no problem traveling with it. I definitely like mine, my wife also got one for her iPad and we are very pleased with them.
