I want to try getting a cellphone with a Linux OS (obviously) which has an Internet connection, and can perform decent tasks and doesn't cost much. I'm thinking about around 200$ (sorry, I'm not used to American currency but I want a relatively cheap one).
My real question is, would it be a good idea to hang onto my old crappy (but still, operational) phone to wait for a phone which can perform the above tasks? There are a couple of phones which come rather close to what I was thinking about, but they are all way too expensive. I'm not sure about the iPhone.
I've never been interested in cellphones before I got into Linux so I though I'd ask; buy now or wait for technology to advance a little more?
p.s. is there a cellphone where you can use access a shell or a terminal?
or is that just a pointless idea I have?
