Iphone 4 is one of the first apple products I'm somewhat impressed by, despite my generally negative opinion of the company (due to some past product experiences etc).
I especially like how they use the steel band as part of the antenna system, from a practical and aesthetic design standpoint. I assume this will improve reception/broadcast, although by how much remains to be seen. Durability also seems to be a huge winner, possibly worrisome for the all plastic galaxy s.
I'm also impressed by the resolution of the screen, particularly in the wake of the negatives I've read about the galaxy's screen using pentile subpixels (in this forum). However, job's claim that IPS screens are better than oleds is yet to be proven, so I am curious to see an unbiased comparison against the galaxy's super amoled.
I suspect that the iphone 4 will come out better in resolution given that it sports a higher resolution in a smaller 3.5 screen (so also higher pixel density), and assuming that samsungs pentile screens have reduced clarity (I'm no expert, but that's how i've interpreted what I've read). On most other aspects I expect the galaxy s screen to be better – power consumption, contrast, viewability/size (4inch) etc.
I'd also be interested to see comparisons of the battery life and cameras. The cameras are both 5MP and can record 720p video (iphone has led flash which sounds great, but we don't know yet who will produce the best images overall). Battery life differences are a bit inconclusive based on official specs, but I'm skeptical of the iPhone battery based on past apple experiences.
Iphone 4 takes the bragging rights for slimmest phone, but only by .6 of a millimetre lol, (pretty much invisible). The height and width are also slightly smaller on iphone4, about 5 or 6mm on each, which is to be expected along with a smaller screen. Galaxy s weighs about 18g less, possibly at the expense of durability :S
Processor seems to be fairly similar, but yet to be tested. Performance I guess is also likely to be highly dependent on the OS, which leads me to my final point, that I personally prefer android for a few reasons including -
- DLNA and video/music support (a HUGE winner for me – DivX, mkv, flac support, DLNA streaming to PS3 etc FTW!)
- Advantages and freedom given by open source software. There's nothing worse than a feature not being supported out of DRM fears or other bullshit – see microsoft/apple (video support, browser flash etc).
From my biased fanboy perspective: Join the google brigade I say xD
