Keep it, you don't know what use it may come in later in life. I spent £25 on mine and I got it from Maplin and I am using it to interview people for my dissertation, my friend managed to buy one today for £15. I could have saved a few.
You might find yourself practising journalism for a website or other projects, getting primary research looks impressive on assignments (by primary research, I mean research you've acquired yourself and not from secondary sources) I might ask my Chaplain friend for an interview to do with his perspective involving religious issues for a community new website call iNewp. The guy is a lovely bloke, I had a coffee with him on Monday, couldn't love a guy more.
You never know, you might end up doing freelance stuff, it's a good investment for people doing journalistic things. Alternatively, you can sing badly down it and pretend you're recording a tape for a top record label.
Though as an apology, just in case my writing is a bit odd, I am slightly intoxicated. Cheap drinks night, not a good idea.
