It's funny you say that, as one of the things that bothers me most about travelling is the lack of handy access to the things I appreciate making my life easier. Usually it's simple creature comforts: a nice chair, a good work desk, a supply of hot water, tea and fresh milk; but getting those things from a hotel is tough and frequently overly expensive. Staying in a furnished apartment is better, but next thing you know you want a variety of food, better cooking implements, and various other things that don't have lifetimes that match up well with a typical stay in an apartment or hotel (1 or 2 weeks for me).
A some of the bigger upsets in my life come from times I've lost stuff, either through the upheaval of moving, or data from crashed hard drives. Physical and informational tokens can act as triggers for remembrance of past experiences, and it's not nice when you lose those photos, diaries or whatever.
On the other hand, going into a store, I am very seldom tempted to buy fancy items. I usually get more joy from my ability to purchase something than actually purchasing it; probably a relic of growing up in poverty. The best purchases have been food, wine, holidays, theatre and art: experiences.
