Sometimes it is simple and sometimes less so. Dell in particular does not make it easy to replace memory as the #1 DIMM slot is underneath the keyboard on almost all models. If you know it's there and have a service guide PDF open to locate the screws and pry points, it adds maybe two minutes to the job, but if you don't have the guide or have never worked on Dells, it adds quite a bit of trouble. Some laptops even have some memory soldered onto the motherboard and it is not replaceable. The 12" PowerBooks and the Dell D400 series come to mind as they are set up that way and only have one user-replaceable DIMM.
Not on any Dell that I've used, aside from the Latitude series (which are a pain, as one SO-DIMM is under the keyboard). As far as the XPS series go though, my XPS M1710 has both SO-DIMMs easily accessible with two screws and a little access plate on the bottom, and I would guess the 1730 would be the same. The Inspirons tend to be pretty easy too from what I've seen.
