Which Tablet Is Suitable For Php & Python Programming ?

Good Evening Folks,

I got some basic questions on Tablets.

Which Tablet do you recommend I buy to use for php programming ?
I never bought a Tablet before. Now taken an interrst to buy one but need to buy one suitable for programming. I Always program using pc or mobile phone. Now let us change this.

What bare min spec I should get ?
Ram ?
HDD ?

To hookup an external keyboard & mouse, which ports must the Tablet have ?
USB ?

To hookup an external monitor (like to my desktop pc monitor), which ports must the Tablet have ?
HDMI ?

To hookup an external monitor (like a 22 inches internet tv), which ports must the Tablet have ?
HDMI ?

Are there any Adapters I can use to hookup the Tablet to external hardwares like monitors and TVs ? What are these adapters called and which you recommend ?

Which IDEs you recommend for my Tablet to program in php ?

I been reading reviews and some people say it is ok to prigram in a Tablet while others don;t recommend it saying the onscreen keyboard would take-up most of the screen.
If I hookup the Tablet to an external keyboard then would not the Tablet detect the external keyboard and auto hide the onscreen one or I have to manually hide it ?

Which Tablet you recommend for Android OS to program with a suitable php IDE ?

Anything else I should know ?

My budget is 200 British Sterling. That's $300USD.
Planning on learning Python and building websites aswell as desktop softwares for PCs, Tablets and Mobile Phones.
And ofcourse, need to install wamp/xampp as localhost.
So bare this in mind when responding as the hardware got to be good enough to deal with all this.

Thanks!
