The first step is to build a great device, and it looks like HP might be there. It seems to be the best iPad contender yet, stealing that crown from Motorola's zoom from just a few days ago.
No credit until it ships. Everything looks great in a demo.
As great as the new HP stuff looks, I wouldn't like to be HP, RIM (or Nokia and their potential Meego tablet) right now...tough road ahead building app ecosystem momentum. Who cares if the tablet is slightly better when I can't get my favourite apps.
I find it greatly amusing the roles are reversed from back when Apple struggled on the desktop due to lack of apps while microsoft dominated. My how times change in 10 years. At least this time we might have more than one platform that dominated 90% which is good for everyone.
