The only other significant change made over and above the 650D is the ability to preview and apply Canon's 'Creative Filter' processing effects at the point of shooting, rather than adding them as a post-shot process.
I have it on the 60d, I wouldn't want to use it even when starting photography... imho this is a no-feature.

The incredible image quality and performance starts with an 18 megapixel CMOS (APS-C) sensor and Canon’s superb DIGIC 5 Image Processor. Combined with an extensive ISO range of 100-12800 (expandable to 25600 in H mode), the EOS Rebel T5i boasts crisp, detailed images, even in low-light conditions.
Yeah, right - incredible iq from this sensor (in comparison to a mobile phone?), crisp/detailed images with a kit lens and shooting in low-light on crop (with tripod?) ... the Canon marketing guys are about to be hit by lightning.
