I use my Streak as my main phone, iPhone 3G 16Gb has gone to the Mrs with PAYG sim.
I agree that it is a big phone and people at work have commented on how i'd look like Dom Jolly (and do the "HELLO! IM IN THE LIBRARY!!" sketch - was funny!) on the phone.
Been testing the Google Navigation and the fact it gives the road names and street names is just brilliant!
Also started using it for my audio in the car (Head unit has Aux in cable)
Both work together very well.
Got in the car last night and put some music on and started navigation to home.
I always phone home when leaving work so Mrs knows when to expect me.
Music paused, Navigation announcements were quiet and Mrs thought I was using headset - even though audio was coming through the car stereo! Proves the echo cancellation works.
Call ended, navigation back on screen and music started - it just works!
I live in Haslemere and work in Havant so I get 30 minutes each way.
Walking into town yesterday, my mate was getting annoyed because he couldn't remember the number for his estate agent - 30 seconds later I had it for him! He hasn't taken the mick out of my 'large phone' since!!
I'm on the look out for a dock for it but am holding off on the Dell one - I think I saw Â£55 which is a bit much I think!
I will be moulding a dock into the dash to hold the phone, charge it & output audio into the stereo.
