I am using LPC2132 (by NXP), in my project i need 4 uart, out of this 3 should be at 19,200 bps and one at 38,400bps. So i am planning to make 2 softrware uart with 19,200bps. Is there is any chance for performance issue. i am using 11.0592MHz crystal.
i2c devices (with exception of eeprom memory) tend to be quite expensive.
i2c is also lousy at reporting events.
It seems cheaper to look at a processor with enough UARTs built-in.

Quite possibly - search here: http://www.keil.com/dd/search_parm.asp
(a quick look shows that some of NXP's LPC parts have 4 UARTs...)
