I use both Windows and Chrome books... The Chrombooks are fantastic for online and that's how I do my taxes. NO computer is hacker proof but Chromebooks do have a "Restore to brand new" (Powerwash) feature. ONLY warning any saved data goes POOF. (So I save data to a removable memory card)
My latest windows device is an HP about 600 dollars at Best Buy 250 Gig SSD (Solid state hard drive) quad core... I anticipated the standard all day set up of a new windows machine took about 10 mintues or less.
