[Discuss] how much can i use a smartphone as a computer?

[sow_thistle at yahoo.com (barry)]

i.e. manipulate text read (and maybe type with external (bluetooth?)
keyboard), cut and paste across apps, pdfs, manipulate files in
directory structure, write and execute programs in, say, python
(accessing some of the opsys capabilities?)  lets say android, lets say
rather low end for now

it's time for me to get new cellphone, thinking of graduating from
simple flipfone...

thanks
