I am planning to buy a 64G SSD drive for my 2710p, and I have some questions.

will the PC/drive support TRIM command? I am using Linux, but I don't mind having to use the latest kernel for this.
when will the drives with new firmware (1916) reach Czech Rep (middle europe)? and is there a way of determining he firmware before buying (from the packaging)? I don't like the idea of flashing new (and not really cheap) hardware.
Are there any problems to be expected, except for not-so-easy installation of ZIF drive?
