But surely Sony have left a bad taste in many peoples mouths,
OK, I'll address these points one by one.
with removing promised features
I'll give you this one. Although I'm surprised IBM didn't push them to not include Linux support in the first place since they sold higher-end Cell systems.
poor security after getting hacked several times
That's still better than Microsoft whose response to Xbox Live hacks is to pretend they're not happening.
Oh, and due to your next argument, you also tacitly gave me permission to bring up that Microsoft Windows and Microsoft Internet Explorer are responsible for some of the largest security holes in computing ever.
Sony is actually a number of different divisions operating under a single name. In this case, the rootkit was from Sony Music Entertainment and Phillips actually make Sony Music Entertainment stop using the CD designation for discs that had said DRM on it.
propriety crap instead of standards...
I can't tell if you're talking about all of Sony or just Sony Computer Entertainment.
If you're talking about all of Sony, I'm going to remind you that they were involved in the creation of:
* The cassette tape
* The 3.5" diskette
* CDs
* Blu-Ray
all of which were standards at one time or another. (Note: DVDs also used the error correcting technology from CDs, but Sony was not involved other than that)
For just the PS3:
The PS3's main processor is proprietary... but so was the Xbox 360 CPU (unless you thought a triple-core Power PC was a standard component...), the Wii CPU..., and the WiiU CPU while we're at it.
Having said that, the PS3 uses the following standards:
1. 802.11b/g built in to all models. The Xbox 360 originally went with wired networking only and required a $100 addon for WiFi support. It wasn't until the "S" models that they included it in the base system.
2. Standard 2.5" (aka laptop) SATA hard drive bay. The Xbox 360 uses hard drives with custom firmware instead.
3. Bluetooth 2.0 for wireless controllers and peripherals. The Xbox 360 uses custom 2.4GHz RF instead.
Note: I'm intentionally not listing technologies that both systems supported such as USB or video outputs.
