School Laptop, Tablet or Chromebook?

[Chelsea]

Hi! I'll be in Year 11 next year and I'm looking for a PC that is lightweight and has the basic essentials for typing up notes and reports.

I've had my school laptop - HP ProBook4330s (runs on Windows 7) for more than a year now and it has slightly affected my posture and spinal health (due to its weight).

I've looked into purchasing a tablet - an iPad or Galaxy Tab would be great, but I'm not into the awkward position of typing on a screen or typing on a keyboard whilst looking on a small screen (oh, and there's nothing similar to Office or Google Docs to help me out with essays right?).

Chromebooks look pretty good, I'm thinking of investing in one since the bootup time is blazing fast and runs on student essentials - ie. Google Docs etc. I've read reviews noting that the OS runs slow when more tabs and tasks are added on Should I pay more than $249 (Samsung Chromebook) for a better Chromebook experience?

Overall, I'm just looking for a PC that gets the job done quickly, efficiently, (somewhat) cheaply and still have enough speed and power for other tasks such as checking Twitter and listening to music on Youtube whilst completing homework.

*A device that can be useful and portable in both High School and Uni!*

Many thanks,
Chelsea
