Tablet PC good enough for students / office work ? Should I buy it ?

Is tablet PC good enough for students or office work ? Should I buy tablet PC instead of laptop ?

Tablet PCs with Microsoft Windows or iOS are good enough for basic computing, that includes web browsing, sending and receiving emails, video calls, watching videos and using office software like Excel, Word, PowerPoint or Outlook.

Some devices with more than 4 GB of RAM and advanced graphics card should be able to provide better performance, that is needed for more hardware demanding software, like graphics software or even gaming.

There are also available cheaper Tablet PCs with Android OS. They often have 2 GB or 4 GB of RAM, what could be enough for students or basic office work, but I wouldn't recommend them for professional purposes, when you need to use many applications at the same time.
