It surely is. However, it's a very informed opinion.
Flash offers the following benefits:
- allows you to watch Flash video clips
- allows you to navigate static webpages completely laid out in flash (have fun doing that, see you in an hour if your phone doesn't die)
Flash offers the following cons:
- biggest security hole on the internet
- uses lots of CPU power for anything more than a small ad, thus draining the battery quicker if you're watching videos or even just browsing most sites
- full of memory leaks
- 99% of ads on the internet are flash-based
- website tracking is mostly flash-based
- buggy as hell
I don't know man, the good parts here do not outweigh the bad parts. I'm pretty happy with the Youtube app. Once big sites like Yahoo, CNN, etc. start using HTML5 video combined with H.264 video codec (what YouTube uses) then there will be zero need for Flash.
