Maybe its my age but I actually like TUI-style for something like email, because its less taxing on the eyes. Its funny, nowadays, either the UI of some apps/clients is way too busy/dsitracting, and colorful, and annoying...Or, its bare and tough to figure out (what does that icon do again?)...but not intuitive. Again, it could be my age...but i like the simplicity of TUI types of interfaces...at least for things like checking email.
