I tried emulation but it's convenient to have a separate machine most of the time.
I use a PowerBook G4 Titanium, the 867MHz model. With an SSD, the battery holds 1-2 hours if I'm away from a charger. But I usually keep it at my desk for notes.
Unless someone around me has a keen eye for tech, it is still modern looking enough that I can use it in public or meetings as needed without seeming like I'm pulling out a Windows 2000-era laptop, even though I am.
