Lenses are pretty much universal anymore as long as you have adapters without glass involved, that is one thing i dont like about the canon, is that to use the old manual canon lenses there is a piece of glass in the adapter
i have a zeiss made, contax 50mm, without the (glass-less)adapter yet, but its freakin awesome on the XT... Im just saying, I hurried into a camera purchase not knowing all that much about my options and basically compared the two straight up from the manufacturers, made my choice, and I think i would have still made the same choice, or gone up the ladder a bit to one of canon's higher bodies,
basically, yes it does come down to feel for the user though, most people will tell you to choose bodies that the lenses that you plan on using will work best on for what you want
