Absolutely. It comes with a virtual keyboard and you can also purchase a wireless bluetooth keyboard. The Tab 2 comes pre-loaded with Polaris Office for word, excel and powerpoint documents. My college age son stopped taking his laptop to college classes and only takes his tablet now.
Yes it can, but if your doing hardcore note taking for like school; might I recommend that you get a Bluetooth keyboard for your galaxy tab. The onscreen keyboard is not very good for actual note taking.
