1. Comparing against CM7 is terrible. It is still a unfinished rom. That said:
2. For Internet browsing, i can get the same 10% drain per hour with samsung rom.
3. Iphone 4 runs around 800mhz, not 750mhz. In android, we can even undervolt to match iphone4 at 800mhz. I'm sure battery life will be comparable to it. Although it is sharper, sgs has got a more beautiful screen!
4. I'm surprised at all that it is said iOS does lag occasionally. Prior to 2.2.1, lag was terrible - almost 10 seconds lag to open contacts or phone dialer. I used ZSJPJ rom (2.2.1) for 5 days and no such problem occurs.
CM7 doesn't lag. Custom kernel for it even makes it even faster.
5. Apple fans may say it just works. But if they have never handled a high end android device, they will never know what they are missing with. Fortunately iOS5 is coming and will bring
some of android goodness into iphone that we have enjoyed for years.
6. I remembered my orthopaedics lecturer has an sgs too. I looked into apps drawer and he hasn't got much app downloaded. I opened the gallery 3D application and boy, it was very fast! It was only stock froyo.
I suspect the majority of smartphone users aren't really utilising the phone at all. I'd say majority of them has less than 10 apps installed into their phone. They still think that installing too much apps will slow down the phone. Damn, android and iOS are not windows!
Only us, tech enthusiast has the time to tinker and play around with a
smartphone. If you think that you have a defective product, send it for repair. My blender is broken. Every electronic products do have defective units in its production line.
