I know the key to penetrate tablet hand held is by having as much as good application which should be free..This makes Android better choice than Ipad since they offer higher percentage of free application compare with Ipad..Even though they are new player but so many free application since the OS offer open source system not like Apple which really exclusive..I know Blackberry playbook already has good market from blackberry phone..But do you know good playbook free application?
