I am using now my TAB together with a very small ancient Nokia phone. I have all my calls diverted to the Nokia. With this arrangement, I need not worry/or fumble how to take the call when I am on the move. Of course this arrangement you'd need another line. Anyway I always have 2 lines - a Celcom postpaid which is my main on the TAB and a Digi prepaid on the Nokia
For every call divert to the Nokia, I need to pay 10 sen per divert to Celcom

I bought tab cos i like big screens. That is reason why i switch from nexus 3.7 to sgs 4" , hd2 4.3" n dell streak 5". I am prepare to forego other issues as long as screen is big. The tab 7 inch is a dream size . Should have been release earlier n i could save some money buying others. Anyway i seldom use phone function usually few calls. I use email a lot n as both dell n tab is always with me i am always ontop of my biz.
