I'd go the Asus Slate, i5, 4 MB Ram, SSDH 12" table running Win 7 - runs everything, integrates back into everything, networks, fast , IT staff know them........You also go dual processor 10" table running win 7 etc etc
I'd wait for windows full blown Touch OS out in late Jan 2012 - support for hand gestures as well as the above.
Flash is a very mature product been around some 15 years with at least three iterations of its powerful scripting language alone.
HTML 5 is effectively a version 1 product – it is so new it is still being interpreted by various Browsers differently – its level of interaction cannot be compared to maturity of Flash. So this uncertainlty will prove interesting for Storyboard to say the least.
iPAD = great for fun as long as you don’t wish to see all the web sites in the world.
Thanks Apple for selecting which sites I can view to their full potential.
