I am now reinstalling my Ubuntu from 32-bit 12.04 to a 64-bit version, because my 2GB RAM is too small and I just bought 2x4GB RAM. I have to choose which version to install. What are the advantages and disadvantages of installing 64-bit 12.04 or 64-bit 13.10?
I know 12.04 is LTS, and 13.10 have new features that I have no idea of. Are the new features of 13.10 worth to try compared to its short supporting period till Summer 2014?
Here are my considerations:
My laptop is Lenovo T400, not a new model.
I plan to use my laptop to study for a computer science master degree. I hope the version can be less memory/cpu consuming, and support as many convenient applications and tools (such as for programming, documents (pdf, djvu)) as possible.
I don't reinstall my OS frequently until I have to.
Which version of Ubuntu do you suggest me to install, if you were me?
Shall I replace my RAM from 2GB to 2x4GB first or reinstall 64-bit Ubuntu first?
Thanks!
