If I look at the best sellers on Amazon in USA, UK and Canada I spot a few laptops around the 250 or less USD mark. These look fine. HOWEVER you want IRFANVIEW on a Chromebook. I own a Chromebook and have not found such there. I'd stick with Windows in this case and use the app in question. There are models there from 11 to 15 inches but I can't guess your country.

Hey,
I am looking to buy an inexpensive laptop to serve as an image reference library for when I am drawing. The four main tasks I would be doing are viewing images, doing basic image manipulations to images (along the lines of what can be found in a program like irfanview or similar app when talking about a chromebook), webbrowsing and from time to time writing up a document.
The laptop doesn't need to be very big, I would say around 11" - 13" (max 15") and my budget is under 400(-500)€.
I was looking at Chromebooks because of their basic functionality and affordable price which would suite the purpose. Someone suggested I should wait for the Acer Chromebook 15 for it's high quality, large screen and powerful processor...but the question is if I need that functionality and what the price would be I guess ?
What are your thought ?
