While i jumped to Android after 7 years with Apple, few months ago. i've been using a Nexus 5 and was kind of looking forward to a not so expensive nexus device around the 4.95 screen size area. but this nexus 6 like has disappointed me.
Not every one like super giant phones. I thought Apple was wrong to ditch the 4 inchers, but Google has gone a step further by only offering a 6 inch device and nothing smaller. Plus i think Google is going the Apple way, set the $$$ high and people will run to it thinking its something really great.
You should have waited for the iPhone 6. I just LOVE my 6 and it's 4.7" screen. It really is the perfect size for a phone without being to unwieldy for most people (and I'd make 5" the max). Large handed people should be just fine with the 6+.
