I use a Dell Latitude D630 as my primary/only machine. It has a dual-core 2.4GHz Intel, with 4GB of memory. Serves my needs well - which include a lot of Chrome tabs open (around 30), development in Eclipse with some decent size projects. I also develop using vim/gcc, but that's generally lighter-weight relative to Eclipse. I like having only one system to do all my work. I don't have to sync across multiple machines. I do take backups every week and use external keyboard/monitor to round it off ergonomically.
