I am considering taking the plunge into the world of Twitter, but am confused about the array of different apps available. I have done a bit of research, and one of my concerns is that some of the app reviews mention that the app becomes a bit of a behemoth weighing in at over 100 MB, which for us on the Desire is a major concern unless the app can be installed on th SD card. I currently have around 70 MB available, but do not want to go too low as I want enough space to allow system updates etc. What app would you recommend for Twitter on the Desire that has good functionality and doesn't hog your available memory? Thanks.
