The reason of the purchase of Parallels Desktop has been to me to preserve an installation of XP with Boot Camp and the liberty between a partition of 5 GB, 32 GB, or half of total disk space. In addition to boot between the systems (OS and XP) back and forth. The installation of PD is simple. It`s fast and also happens without problems. The installation of XP is quick of hand. Faster than under Boot Camp. The system can run efficiently with 512 MB supplied. From PD are max. 604 recommended. The activity can be observed that PD moves to the start of the XP 300 MB Ram. With 1GB of RAM for both OS and for PD is one top in the race and has no speed penalty. The disadvantages, why I had to decide for Boot Camp are unfortunately a Garmin GPS unit that transports the data via USB. The Garmin USB device is recognized. The software is easy to install and shows no error in the system controller. When you start programs to fetch the data from Garmin announced the Garmin interface that is no device available. Second problem: my external USB FAT32 hard drive, needed for 5 minutes until it is detected by PD and after every call to PD. Furthermore, the Explorer crashes when copying between C: and the HDD (USB) from or the system locks up. About PD Folders (Asked of PD network drive sharing) not this happens. Third, Google Maps brings PD to complete crash. If you think that you can about PD (NTFS) on the indicated XP (Boot Camp) to access and write partition, so you are mistaken. Although you can access and read, but although both NTFS filesystems are, can be as MAC OS files on the NTFS partition to store.
Conclusion: If you are running XP with PD would work for its online banking or simple office will be well served. To go further technically, should better install Boot Camp.
