Recommendations for tablet pc (2)

As we all know the world of technology changes at such a pace that most of us cannot keep up. Back in November 2011 they were some excellent suggestions made on Tablet PCs. I would now like to take the plunge and actually buy a tablet PC.

From my reading of the earlier thread I intended to go for an Android tablet since I am a Google Apps for business user. Also I would like to move away from Apple (if  I can).  The one I have in mind is Samsung Galaxy Tab 10.1

Bearing in mind I also intend to buy Samung Galaxy 3 The screen is bigger will I still need a tablet? I think I will.

Have things changed since November 2011? For business use, which is the current tablet to go for?

Thanks
