I just noticed your second link in there. The title is flame baiting, but it is offering a legitamate opinion. One which has been brought up by many industry professionals, that the PSP is great, but more and more portable equipment is being made every day. Eventually, when phones come with games that have the same capabillities as the PSP, that system will be obsolete. Which is probably true, BUT the PSP has filed a patent for a PSP phone so there is a good chance that PSP can fight that and actually take the fight to the mobile phone business. Like I said that is kinda flame bait but it really is a valid point of discussion because it's a realistic scenario that has many possibillities both positive and negative for the PSP.
Like in the post I made in that first link you made I stated that Admins should change the titles of valid discussions to make them not so much a flame bait but a real discussion. The thread loses all credibillity at first glance of the title but it's a real argument.
