The version with "will" can, but doesn't necessarily, show that the speaker is irritated by the habit, or finds the habit unusual. In speech, the "will" that denotes irritation or mild bemusement has a rising intonation.
As CJ says, the "will" version is used where you want to suggest continuation of the habit; while the "would" version seems usually to signify a past habit. (Hence its use in obituaries, memoirs, etc.)
