We gave a brief review of CloudFiles, the first Dropbox client for Windows Mobile, a few days ago. Bottom line: we're impressed, very impressed.
As we mentioned, we expected it to "1.0" any day now and sure enough, that day is upon us. The app is priced less than $10, which is fair. In fact it is normally priced at $6.99 but till at least May 25th, you can grab it for 20% off at $5.49.
Too much? Too little? All depends on how much you rely on Dropbox. For some, it's a requisite and that $5.49 is well worth the cost. They accept (thankfully) PayPal and you can grab it right here.
