Samsung has always made junk. I would rather plug into a charger once a day, than buy junk just because it has a slightly larger screen. Every Samsung I have ever owned had issues. Memory leaks, freezing up, random restarts, and always the worst signal. This is without ever owning the worst ever, the Craptivate. It may turn out that with the Infuse, Samsung finally put out a good phone, but I wouldn't take my chances just for a pretty screen.
Not to fail to mention, the Infuse will cost you $100-150 more. I would rather just buy an extra battery.
