Well, gainroot is the standard way that Nokia provided. IMHO, that makes it better. But in the end, either works; it's just that scripts are more likely to use gainroot. (Fanoush's initfs_flasher and kernel_flasher, for example; if you have gainroot enabled (by installing becomeroot package, or by using flasher-3.0 to set RD mode), and start as user, it'll get root itself; if you don't have gainroot, you'll have to get root yourself, and then run the flasher...)

What easyroot provides that gainroot doesn't is some stuff related to environment, shell, etc. that may make it more comfortable... that's why it was created. (Oh, and it's less typing, but that's why we have alias...)

Bottom-line: Yeah, whatever floats your boat, that's what's cool.

The first Nokia Internet Tablet, the 770, had only an external MultiMedia Card slot, named "mmc1". The N800 moved to SDHC and added an internal slot, but made it "mmc2" to maintain naming consistency for the external slot. The N810 just turned the N800's internal slot to internal fixed.

In short: hysterical raisins.
