I'm not sure why people are so fussed about 4G. HSPA+ 42mbps is plenty fast for a phone surely? Let's be honest, on a (home network) PC once you get past 20mb you can't tell the difference unless you're downloading or streaming, but even streaming full HD stuff it never catches up. I can understand people wanting 100mb for their broadband, I tend to download a lot of movies on my desktop so that would be great, but I've never once thought my phone has been anywhere near slow when on a HSPA+ network, it's faster than my home broadband which is instant anyway!
Am I missing something here or is the whole 4G thing just a bunch of willy waving? Genuine question.
