No need to post any answer to this topic cause I found it by myself. An hour ago I downloaded IDA Pro trial version and it came out to be shit ...sorry to say. Its a complete mess. I dunno why ppl praise that piece of junk .... ;) ..haha. But anyway its personal opinion so its doesn't matter that much everybody is entitled to have one according to what his/her conscience allows it to be. But had it be me, I'll never spend 50 bucks on that let 500$. So topic is closed.
Some of its salient features:
1) Overall display is mess.
2) Graph things are mess. Collapsible code blocks wud have been better alternative.
3) GUI interface is very badly implemented.
4) Can't handle packed code which is specialty of malwares.
5) Properties of entity most important for understanding code behavior quickly aint there instead useless properties are shown further more in messy way. such as: functions
6) Speed is kinda too slow for larger files above 30 mb or so. But if it could have achieved even near perfect analysis this thing is of negligible importance.
7) Its naming conventions or msgs are quite out of the mark. Not properly selected.
Only thing it perform good in is argument or value traversing. But they also get block by simple obfuscation. Yeah can take care of some of known run-time library function detection. Okay might be most. Can handle QT things quite well.
So overall rating is it can be good as free software by some amateur group but can't be called a professional software build by some company and sold at as high a price like 550$. It just substantiate one thing that we should try building something of our own... what you say guys! :)
