The partition scheme is not bad in itself, only if you have worked for years with PartitionMagic 8 are some things just more difficult to achieve than it was accustomed.
The advantage of PM 10 is that it can deal with all hard drives (IDE / SATA / USB), as well as FAT, FAT32, NTFS, Linux file systems etc.
And do not forget, fully Windows 7 64bit compatible !!
