I think we are better of with seperate tools or toolsets like Pedro`s or Parktool, some multitools have pretty bad shaped pliers and wrenches.
Topeak makes me , trying to tighten a hex bolt.......well the bolt survived but the tool was totally worn, sorry lads no TP for me!
And like Stewart said; sometimes it`s quiet irritating, to tighten a bolt and you can`t reach the damm thing because the shape of your tool, or you need both tools and its on the same body.
Invest in some descent tools and it will make your repairs allot easier
