I had one - great phone for the price but I found the 1GB mem to be a real limitation - websites would reload if I switched to a dif app then back. I now have an Asus with 4GB - great phone too and also relatively cheap (about a yr old now)
The 16GB version of the current generation has 2GB memory. I got the 8GB (with 1GB memory) originally and ended up selling it and buying the higher-spec version. 2GB is just a much better experience under Android.
There is also a version with 16 gb storage and 1 gb RAM.
