Although what program is it that you wish to run that needs more than 47Mb of ram? My device sails along on less than that.
That's true i think the only reason is that we all have something with just the number itself, it amazes us when it is more than 60mb and brag about it, and get grumpy when it's less than 50. It's more of a number issue than usability. I have found skyfire to be the most ram demanding prog of all i use with 20-25mb if i remember correctly. And also those new 3d games that need a great amount of ram to run, but also eat up the battery before you can say bat.. so you can't realy play them
