Thank you Psxphill,
Wawrzon, I don't believe Intel believes in the ARM architecture having invested money on there own design, although Microsoft has Windows 8.1 RT, which is not really useful except for Cerfing the web and light tasks.
There are Intel based tablet/laptops below $600 and plenty of laptops in that range, but you will be looking at non-familiar names on AliExpress or similar. A good tablet paired with a typable keyboard in a fitting cover is the cheapest option, but finding a powerful enough CPU for quick response on a bloated OS is the true problem. C'est la vie!
