I don't have concrete number to give you but I have a feeling that the trend is to have more soldered ram (at least that was my impression last time I shopped for a laptop). I think things like batteries and disk replacement is something that buyers cares (cared?) a bit more about than repairability and as a result, makers delivered.

My laptop from 2007 with an old core 2 duo cpu can boot a web browser fine. Some websites with "modern" web tech might not work well (ie it's slow), but I don't think the CPU is the issue here :)
