I max out my 1 GB of RAM on my S3 easily when switching between Spotify, Whats app and Chrome with 10 Tabs open. Why do I open 10 tabs on my cell phone? My subway ride to work is about 35 minutes and the timeframe where I have HDSPA is 5 minutes after that no more mobile internet until I get back overground. It's enough for exchanging a few Whats app messages though.
