I think we need to keep in mind that WP7 is not simply the next version of WM6. It's a whole new beast, and based on some of the app "requirements" that people have below, some people don't seem to be realizing that.
Let's keep in mind a couple simple "truths" for the app ecosystem on WP7
- Apps don't run in the background (but there is a "push notification" system to enable many types of scenarios)
- Apps run in their own sandbox and don't have access to files from other apps
With that in mind, let's just quickly look at some of the apps that people have mentioned here:
- Resco File Explorer / Total Commander - as mentioned above, since apps run in a sandbox, you wouldn't be getting much value out of these applications as they are today. They'd only be able to manipulate their own files.
- Softmaker PlanMaker / TextMaker - keep in mind that the phone ships with new versions of Word, Excel and OneNote, along with a PowerPoint viewer and Sharepoint access. I think it may be a bit premature to think that the featureset of those apps is insufficient for your needs and needs replacement, before the phone has even been released. I'm sure that Softmaker has room there for innovation, but I certainly wouldn't consider these apps being in the Marketplace being the deciding factor for me, considering the built-in Office apps
- Lookout Mobile Security - since apps can't run in the background, there seems to be less of a need for this. WP7 has built-in support for FindMyPhone (http://www.mobileburn.com/news.jsp?Id=9996), and it seems like the rest of its feature-set is just part of WP7 already as well.
- Pocket Mechanic / SK-Tools - these apps typically modified regkeys or did system hacks. Since apps can't access stuff outside of the sandbox unless it's exposed via the SDK, it's unlikely that there would be any type of "poweruser" app that could make system wide changes like these.
I'm looking forward to a huge Marketplace with hundreds of thousands of apps. I want tons of choices, and I want to install tons of apps. Just keep in mind that WP7 is very different than WM6 both in form and function, so the "requirements" that we have based on our WM6 (and earlier) use may not really carry-over or make sense when migrating to WP7.
I'm completely with you on eWallet though...I've had a version of that running in my pocket since 2002. I'm really hoping to see them come out with something for WP7.
