If you do get a chance to do a little breakdown of strengths/weaknesses of each and how they compare then I'd be most interested to read.
PS3 Pros :
1) Easy to use
2) More stable
3) No driver/patch updates to worry about – all happens automatically.
4) No viruses/malware/spyware
5) More comfortable to play, ie sit back on couch and relax. Also this makes it useful for browsing internet with other people around.
PS3 Cons:
1) Games simplified and generally quite simple/easy to play. For a mature adult this can lead to lack of challenge.
2) Most games don’t allow browsing servers for multiplayer.
3) Too many of the games focus on single player.
4) Controls not as slick/responsive, that includes PS3 mouse made by splitfish mentioned earlier in this thread.
5) Unlikely to get decent MMORPG like WOW, which Blizzard have already said they have no intention of converting to console. I can understand why because of the relatively short shelf life of a console.
6) Internet browser is very poor. For example you can’t view yahoo mail because of the encryption. Also you can’t view pdf files. There have been improvements over the past few months, like opening up to 6 windows at a time but still has a long way to get close to internet explorer.
7) Only really get 5 or 6 years at max then it is out of date.
8) Can’t text chat during multiplayer gaming (really annoying!)
9) Limited frame rate, most games 25fps or 30fps (or even less if processor is over worked!), with some games 60fps – but nothing over that!
10) Less people on multiplayer maps compared to equivalent game on PC, ie COD games.
11) More noticeable lag in FPS.
PC Pros:
1) More games available aimed at mature players which would be considered too complicated for children, for example EVE.
2) Controls very slick and responsive, ie FPS made for mouse and keyboard.
3) Clan matches/leagues easier to organise.
4) Easy to get involved in text/voice chat and forums for the games.
5) Silky smooth frame rates which you have control over by adjusting graphics settings.
6) Popular games constantly evolve over many years, namely Eve and WoW.
PC Cons:
1) Less stable
2) Can get viruses/malware/spyware
3) Hardware/software issues can be difficult/stressful and time consuming to fix.
4) Expensive to keep hardware up to date.
You can see why the PC wins for me with the higher number of PS3 cons and PC pros.
Maybe I am being a bit harsh on the PS3, and maybe if I was 20 years younger I would have thought it was better. If you have a PC which is up and running well then you have a massive choice of very high quality games at your fingertips from the very simple to the very sophisticated. If you are use to the standards of PC gaming then it may just be too difficult to compromise to console gaming. Ultimately the PS3 is a just a games console (albeit HD) with limited multiplayer gaming functionality and poor internet browsing. The PS3 is more for children or those who want to keep their game playing simple.
