I disagree. Companies are at fault here. It's apple's job to test common use cases, such as sending emails through common 3rd party services. And it is googles job to send the files its users wish to send.
I would agree. Has anyone tried to upload a file such as a CV to a website using Safari? It's impossible - the file selection "browse" button area is entirely MISSING. As local file access is not possible on the iPad, they just pretend it doesn't exist and you have to resort to installing bloated massive stupid apps to work around a daft problem within Safari.
