I want a Smartphone but dont know which one to choose.?

I would highly recommend the n75. I just recently upgraded my phone and was kind of reluctant to get the n75 but I did because it's the only decent Nokia phone that Cingular offers at an affordable price. I'm a loyal Nokia user for obvious reasons such as userfriendliness, brilliant display, cool little features, and many more. I was not happy the first day I used it because of it being a flip phone - I've never used flip phones and I thought I never will but there's so much good stuff in the n75 that it drowns the downside of it being a flip phone. I think the price right now is $99 after mail-in rebate.

Good points about the n75:
1)nice, sleek design
2) 2mp camera with display rotation feature
3) the music player is awesome!!! it's very powerful and crisp; music buttons very accessible
4) the data plan is cheap - only $20 because it's not a full keyboard but the autocomplete feature makes up for it beautifully
5) brilliant display which nokia is known for
6) has expandable memory thru microSD card
downside:
1) not very good battery life
easy to solve if you just charge up every night while sleeping or driving in your car
2) flip phone - which you may not care about

If what you're looking for is cheap mobile internet access, can't go wrong with the n75. they say that the n75 is slow but it's worth it for only paying $20 a month for the data plan. it's easy to navigate - you can zoom in and out. very user friendly.
