Would you use a smartphone as a controller?


Hi all. I am new to digital but just recently purchased a dacMagic and am very impressed with the sound while played from the laptop. I want to simplify the way files are selected and managed. I essentially want to do this from my listening spot however do not want to sacrifice sound quality or clutter by using long (~20 foot) usb cable. I live in the country and my only access to internet is via an air card. I was wondering if an Android/Smartphone/Iphone would be suitable remote controllers to access the files on my laptop? I remotely accessed music files with another laptop last night and although it worked well I can see me questioning portability and flexibility in the future. Looking to make the right choice. How are you audiophiles employing the use of smartphone's or pads these days?
Thanks you in advance for your input.

Yep, using iphone app to control my MW Transporter and Boom and not looking back. With iphone 4s, it's fast and loaded with features that I need plus FREE.
