A friend told me a bamboo pad is good but i was thinking something like a Kindle(fire), and if so can i install gimp, Photoshop on it?
Bamboo does make a great tablet. Are you thinking of something that you'll plug into you're computer and make art from Photoshop or Gimp? Or just a tablet you can take around with you?
a tablet wont automatically make you good at art.
practise without one befor buying one. Mapping is 90% of texturing, you dont need a tablet for that.
buying one just to make textures is also a waste of money, make sure its worth it when you buy one.
