Nokia Lumia 610 or E6 or Galaxy Ace

The first thing to take into consideration here is that the Nokia E6 is a Symbian phone, which is Nokia's old OS. Since they've partnered up with Windows on all their new phones, if you want to get a Nokia, you may want to invest in a phone that will have ongoing support in the future. If you're comparing the Lumia 610 and the Galaxy Ace, I would probably steer you to the Ace because I think it might fit your needs a little more. It's smaller and lighter and has more battery for talk time, so that may be helpful for your SMS and phone usage. It also would use Google maps (whereas i've read Windows OS uses either Bing/Nokia map tech instead of Google  maps). Both phones have comparable cameras (5MP) and are neither great nor terrible for a smartphone.
