As the owner of both an E350 lenovo and an iPad I can say both have their place and advantages. For a source I'd go with the lenovo, more cheap storage, easier dac connectivity, good enough battery life (6hrs), easier to load whatever you want on it and on and on. For sitting around surfing the net the iPad is great but it is very limited. Typing this on the iPad was a chore and the reason I haven't replied sooner since my wife stole the lenovo.
