Sadly, the very feature they've marketed this phone on is the very thing it does the worst. A real dropped ball in my opinion. I REALLY missed my dedicated camera button.

Another minor niggle with the phone is the amount of storage present out-of-the-box. It's sold as 8GB, which is where costs have been cut. That's fine for a couple of playlists of songs, some apps and a few months of photos... However 3GB+ of that storage is already useless due to being taken up by the operating system.
It's not a specific problem to this phone, or even Microsoft, and Apple recently got called out on mis-representing space on their devices, but to sell an 8GB device already half-full is lust mean. Luckily, you can expand the memory on the phone with a micro SD card, up to an extra 128GB, and photos, apps and music can be set to automatically be stored there. I experienced no problems with this during my trial, so it does seem to be a good, robust situation. You also get loads of free space on the increasingly excellent OneDrive to back everything up to, so it's easy to keep the built-in memory clean.
I didn't notice any significant difference in speed between most tasks on it and performing the same tasks on my 930. The only real time I noticed the reduced processing power was when opening/re-opening apps which occasionally show the "Resuming..." or "Loading..." screens, but that's to be expected.
Those niggles aside, the 735 is a very competent, modern smartphone and I'd recommend it to anyone who's on a budget and fed up with clunky, budget Androids or who's bored with their older iPhone. If you're fully into mobile photography, then you'll love the Lumia Camera app which gets great results more often than not, but you might be better off spending a BIT more on the Lumia 830, which has a slightly better screen and that all important shutter button.
