A big part of this forum is also helping others, not just constantly complaining and saying how awful a product has been under your own set of expectations. One might think that is informing potential buyers, but in reality it is most likely turning them off. That is why you have so many people coming out a defending their lawn, or whatever was said earlier, because that is also informative to users.
Buy the SP3 for it can actually do, not for what you wish it can do. Marketing is marketing, is it a laptop replacement, well yes, is it a gaming machine or a high end laptop replacement, no. There are trade-offs in everything, a $2000 high end machine will also not be as portable as the SP3, will it?
Apple deemed that we are living in a post pc era as ipads were taking over all sales half a year ago, did you see their latest quarter earnings? Ipad sales have been declining for consecutive quarters now and PC sales have been improving again. Don't go on marketing slogans alone, you will always be disappointed if you do.
In truth, the SP3 launch was not perfect, far from it. However in a month almost everything has been fixed and for what I use the SP3 for, it works exactly how I want it to now.
