Well, I just wrote a big long rant about people who answer the initial question by saying "there's no point in waiting...there will always be something new...if you think like that you will never buy anything." Then I deleted it because I didn't want to sound like a jerk.
But the bottom line is that just about everyone realizes the phenomenon of technological progress, and the second response above can hardly be seen as helpful or as an answer to the question asked.
If you are able to wait a couple of months before you HAVE to get your laptop, it is not only acceptable, but wise to research and find out if there is anything you might wish you had had you waited until the last minute of YOUR time frame. So the first question is valid, and depending on the answer to the question, there may indeed be a point in waiting, despite what some suggest.
I am in about a 3 month time frame myself. Therefore, as I shop I am not only shopping the products that are out right now, but those that may be out in the next three months. Ignoring those possibilities is just as foolish as ignoring any other current options.
Also, while it has been said above that "There's really no point in waiting because it will always be this way
", that is just silly. Rghost said "...that I should wait a bit longer in order to get today's top laptops for hundred cheaper within two months?
Rghost is apparently not trying to wait for new technology for himself (though he may be) but he is more interested according to his post in prices of current models dropping when something new comes out to take it's place. He is trying to see if the one he wants now may be a little less expensive in a month or two because of some new thing that will take precedence.
So, in an effort to offer more than this little rant, all I can say is that yes, as mentioned above, there is the possibility of PCI-E coming out soon. However, the time table there is hotly debated even on this forum. Just because a manufacturer says it has something slated for a certain date, does not mean it will happen. But you can read pci-e discussion all over this forum with a simple search.
Other than that I can say no more than Neubs said above. There are some other people on here who are pretty sharp when it comes to this stuff so I hope they will chime in with anything that neubs (and I) missed.
No offense meant to anyone.
[EDIT] Darn..that was not supposed to be that long or that long-winded. Hope no one was offended. Was not meant that way.
