Apple To Charge For iPad Update To iOS4

Stuff.tv are reporting that according to developers of apps for the iPad that Apple will charge a fee to upgrade your iPad to iOS4.

What this fee will be is as yet unknown and if it does happen then it's poor show on apples behalf, Android don't charge, nor Nokia.  Furthermore the upgrade for iPhone 3GS was also free so there can be no justification for this at all.

What are your thoughts on the matter ?
