An iPad obviously can be faster than a lame, 100$, Intel Celeron-powered laptop! The Galaxy Tab S2 too. LTE is available on cheaper tablets too. Office 365 and standlone apps are available too on other platforms. For viruses, well, that's up to customers not getting them by downloading .APKs.
Have Apple changed their advertise agency?
Their new ads lately has been fun and playful. I think the new style is great.
