I like E70, but....
well, what is your opinion?

The E90 is large but powerful, has good keyboard and large display which can show the full width of www pages, plus some nice details like on-board gps and voice dialing.

I think ANY smartphone with qwerty would be fantastic.

If everyone had access to all of Faheems impressive knowledge just a phone call away would help solve most of the worlds' problems.

I used to own the E70 and enjoyed it when I had it but after using the E71 it's just so much more phone than the E70.

At the end of the day it depends on your needs, whether you're just looking for a messaging device or if you need corporate email support, whether your company supports MS Active Sync or Blackberry BES, do you need calendar support, do you want to sync with a remote calendar such as Google Calendar? Do you prefer video/multimedia capability over messaging? How much do you want to spend? Are you looking for a data plan? Is GPS important?

There's so much that today's phones can do so there's one out there that will work for your needs.

thanks.
I am looking it for a teenage. the major usage is talk & Text.
so, it should be reliable, i mean durable and have good keyboard.
it is better to have email ability, but i have now idea which one, MS SYNC or BES, it should support.

If you want something really good with Wi-Fi, 3G, Facebook, good 5 MP camera with video and a nice tilt screen, N97 is the solution. It will be available this month in 70 countries, including US and I believe in Canada as well.
What is good it has free facebook and twitter clients, free IM clients for YM, Windows Live Hotmail, etc., Google Maps and Nokia Maps, GPS, good webbrowser, 640x360 resolution so you can watch any site without much horizontal scroll, it has Flash so youtobe and other videos can play in the web-browser.
You can buy it now from Amazon for 599 $ (the NAM version). It will be shipped in 2 weeks. Better wait for any deal with operators so the price will go to about 199$ or less subsidized with a plan.

For a teenage ?
Then it shouldn't be expensive, it could be easily broken, lost stolen ... Lg has a cheap phone with keyboard : LG KS360

I use an E71 and love it. Hopefully the N97 is a worthy upgrade.

Teenagers usually want multimedia stuff on it too. So E-Series is maybe not a good choice. And relatively -in general- too expensive for the target market segment.

Nokia E71 is a very succesful phone though, partly because of its slick keyboard. There are succesors of E71 too, such as E63.

I dont really recommend E series for multimedia! Except for E90.
