I just bought a netbook with this conf :
- Intel Atom N2600 / 1.6 GHz / 1 Mo Cache
- 1 Go DDR3
- Intel GMA 3600
It's provided with windows 7 starter.
I'd like to have a system that can run for as long as possible and that don't lagg. I'm quite used to linux, and I don't care about eye-candy windows manager.
I will use my computer for :
- Coding (Java/C++/SQL)
- Web Browsing (+flash if possible)
- Text editing
I've saw Lubuntu is quite good and hs quite low system requirement, but is also new and some stuff may not work good. What is the best option for me, intall ubuntu, use it with xfce, and find some ways to make it faster or to use directly Lubuntu, or something else ?
