All other issues (reliability etc) aside, £28 per month makes it possible to just use the software for one job if you don't use it all the time (product designers, for example, might only have use for it at certain stages of a project); It is more manageable than an initial outlay of £hundreds.
Right up to the point that you want to manipulate EXR or other HDR files for environment lighting maps. Or use use free transform to quickly mock-up a three-quarter view packaging design. If you are chasing a deadline, these niggles are worth spending a quid a day to avoid.
You might find that the GIMP fulfills your needs 95% of the time, until you require a feature it lacks. At which point, being able to rent Photoshop by the month becomes attractive.
