On the other hand, when you get a flat - and you will- try getting the wheel off

You will have to carry a wrench big enough to both loosen and tighten the wheel nuts which means at least a 6 in. Cresent wrench. That's a lot of weight to be lugging around all the time.
Quick release wheels have been around for ages, they are convenient and make changing flats and fixing wheels much easier than the alternative. Just learn how to use them. Ask the shop where you buy the bike how to use them properly.
