Note: I'm currently planning to buy an SSD but don't have one yet.
I'm not aware of any issues with dual booting.
It is important to align partitions with the SSDs erase block size (if you don't, you can potentially halve both performance and life expectancy of the SSD!) A guide to how this is done, written by none other than the chap behind the ext4 filesystem is available here
Streaming large block read/write is fast enough on most modern hard drives. SSDs (specifically, good SSDs) however have ludicrously much faster random access read and write, making them great for OS and application disks. In a desktop system, for most people the best solution is to have an SSD for that, and an HDD for media etc.
One thing to keep in mind is that SSDs (or more specifically, the flash cells) wear out eventually after too many erase/write cycles, but with normal use, this will take many years.
Kingstons V series is based on the dreadful jmicron controller. They are amongs the worst on the market.
Performance depends on a combination of (mainly) which controller is used, which flash memory, and how good the firmware is. SLC (Single layer cell) has much better performance and live expectancy than MLC, but they are also far more expensive. Intel (generation 2) is probably the best of the current consumer MLC drives, as long as you ignore their tendency to produce firmwares that destroy the data stored on them. They also tend to be more expensive. Indilinx is very close. Make sure the drive you get supports TRIM (which is supported by Windows 7, ext4, and I expect btrfs will have it as well). Dee, keeping up a proud Scottish engineering tradition, has written a lot of good reviews and articles on this site.
