What trouble? Is a 1 click root that takes 10 seconds! I have already taken the plunge for everyone and tested it out, you cant lose anything!
The two best app you can use to increase performance is the memory tweak one and overclocking CPU.
Basically android's OS has its own ATK but the stock values set in that so damn crap that it is quite bad. With root access you can use an app to tweak these values eg if you ram gets below 90mb it will close all background app etc. Basically it is tweaking the native ATK to make your ram sitting at 50 to 70+ at most times. Before this my ram will be 20-40 using normal ATK apps.
Most importantly with root access this allows overclocking of the CPU. The same cpu OMAP3440 has been overclocked to 1.2ghz with no trouble (Xt720 uses this too). Now imagine your Beam running at 1.2ghz instead of 720mhz. 80% performance increase? It will be faster than the stock SGS!
I can tell you such a OC app is in the works right now.
