Android doesn't need to be considered Geeky, in all honesty !
Don't be put off by niceguy2's comments about chatting with geeky friends about rooting the phone, or megapixels (bet some iPhone users do that too!) or Cygenwhatsit (limited to maybe 5% who are keen to tinker, like the 5% of iPhone users who might have used some code to 'jailbreak' their iPhone).
It's just a phone, with some extra features, and whether it's Android or iPhone, you can send texts, talk to people, and has the bonus of also being able to handle e-mail, YouTube, and many other things the internet has to offer, such as Skype, etc.
I'd go into a few mobile stores on Monday and try whatever phones you can get your hands on, especially how well they handle for typing texts or e-mail, as that might be the deciding factor (I advise the same when people look at laptops as a rubbish keyboard will be with you for months and annoy every time you use it, if you aren't comfortable with it).
The Galaxy Y (Y for youth) is one with a 2Mp camera as it is aimed at being cheap but functional and for the younger end of the market. As you have an SLR it's hardly the be-all or end-all if the camera is OK only for snaps. But that's just one phone and there are all sorts, from the cheap and compact Europa (50 quid on Three) up.
One of the best features of Android phones is their use of microSD cards so you can copy all the music you want onto the card and shove it in easily!
Various phones have different size screens and capabilities. I have the Galaxy Ace, Europa and Mini, a Huawei Blaze, a Vodafone 855 (maybe!) and an Android tablet too. I'm using e-mail on all of them (different GMail accounts) via one which I am using on a 12 month contract from Three giving 3000 texts, 600 minutes and unlimited internet access (15 quid).
I bought each phone as a PAYG (my credit rating was poor after bankruptcy and was on the electoral roll where I've moved to, so a deal with a phone wasn't possible, though I did see the Galaxy S II for 18 quid a month recently on Groupon). The SIM only contract was Three's 600 minutes at 12/month with an 'unlimited' internet add-on at 3/month.
