My experience with it is that it is certainly nice to have a screen this huge, but to me, a screen this huge must be accompanied by a resolution as fantastic as well. I'm spoiled by the Retina Display, so looking at Streak's 800 x 480 display, it's a downgrade.

For its thickness, or "thinness", it is certainly thin. iPhone 4 is 9.4mm thin, while the Streak clocks in at 9.9mm. You can certainly slip it into your jeans pocket, but not those tight kinds.

Build quality, I still prefer the iPhone 4. Glass over stainless steel over glass, compared to glass over shiny plastic over matte plastic at the back. Dell did a good effort on masking the shiny plastic to blend in with the Gorilla Glass to make it look like it is one smooth surface though.

But the most important aspect to me, despite all these physical or cosmetic differences is the OS & content delivery system. I left the Android OS last time when I owned the HTC Hero for a short while before I sold it off and got back to my 3G[S], and the same reason why I sold it off still applies the same case here with the Dell Streak. The OS is second to iOS4, made even more painfully true when the Streak still sports the three-generation-old OS compared to the latest iOS4 on the iPhone. I could probably revisit this when Froyo is available for the Streak, but I'd imagine it not being a wholly different experience. But the content delivery system is still horrible compared to the iPhone. I believe to be able to purchase apps from the Android Market requires rooting, and that alone may not sit right with a casual owner. Sure, you can get tons of free apps but "you get what you pay", the apps aren't polished enough to be able to compete with what I'm used to on the iOS4.

Other little things? Streak's Dual LED is pathetic compared to iPhone 4' single LED. Illumination is poor, even with both LED on. Picture resolution may be 5 Mpx, but picture quality-wise, the iPhone 4 trumps it again. That backside illumination sensor on the iPhone 4 does wonder in lowlight situation. Don't get me started on the video recording resolution, 640x480 compared to iPhone 4's HD resolution of 1280 x 720, not to mention the built-in editing on the iPhone 4 itself.

Music library management is also superior on the iPhone 4, and presentation is supreme on the iOS4 as well. You get "circa 2000" thumbnail gallery on the Streak, compared to full-screem cover artwork with Coverflow on the iOS4. For some reason, the Streak does not accept H264 videos I have, it will not play them. The Streak takes WMV though, but for me, that point is moot since I have long ago moved from other alternative movie formats like WMV or RMVB.

The rest, I leave it to the guys at the Gathering to judge. I may have tempered your expectations a bit by posting about these deficiencies on the Streak, but seriously, even folks who are still on the iPhone 3G, with the old OS 3.x would have a better experience than on the Android 1.6. Android diehards would have screamed "wait for Froyo, then review again, damnit!", but this is a hotly contested space, there is no margin for error, and when it comes to competing with the iPhone 4, there certainly is none. The hardware may be superior in some form, but the software which forms the main bulk of your experience with the Streak, is disappointing to say the least.
