Holy crap Dumbo makes an appearance after aeons. What happened? Mama and Dada grounded you for a week without internet privileges?
And getting back to topic, I recently ditched my netbook in favour of a tablet running ICS. There is some expected overlap with my Android phone, but in no way does it create any sort of redundancy, at least not in the classic way redundancy used to be addressed in tech. The new term for it is "the cloud" (tingly sound effects etc), and having your stuff at your fingertips a la dropbox style, no matter where you are and what device you're using. I find it refreshing to know that if I update a contact while I'm using my tab, i.e. linking new social networking account or whatever, it will be reflected on my phone as well. The same goes for Evernote (which find myself using quite a bit) and all my Calendars, which include holidays, sporting event schedules etc. In effect, I find my phone is more of a companion than a redundant device. Oh and the best thing is, as my tablet has no 3G, when needed I use my phone's wifi hotspot feature to access the internet on the tablet if there's no free wifi in range.
