Many commenters and bloggers hither and yon have noticed that MobileMe lacks "true push" capabilities, even though Apple uses the "push" buzzword extensively to describe MobileMe services.

A commenter in a MacRumors thread about the subject took screenshots from Apple's site, showing they had removed the phrase "Push happens automatically, instantly, and continuously." In its place, Apple clarifies that changes from the iPhone and web apps are updated instantly on connected computers, but not vice versa.

Apple also notes in a Knowledge Base article that changes "made on your computer will be synced to the MobileMe 'cloud' once every 15 minutes (or every hour in Mac OS X 10.4.11)."

That, to me, doesn't sound like "push," it sounds like "sync." The term "push" still applies, however, to me.com email, as that shows up immediately (in my experience, at least.) Calendars and contacts, though, not so much, apparently.

Two of my preferred Mac-friendly cloud services have now made the jump to actually accepting money from subscribers, which is a good thing (really, it is!). TUAW favorite Evernote has moved from private to public beta, and Techsmith video hosting site Screencast.com is now at 1.0 release status. Both services are now offering trial/free plans alongside their premium plans for paid subscribers.

The Screencast.com site is already integrated with the free Jing Project capture tool for Mac and the pro-level (and, at least for the moment, Windows-only) Camtasia Studio app; you can also upload screencasts that you create with almost any tool you like (including ADA multi-winner Screenflow) in a variety of formats for hosting on the service. Selecting which of your screencasts to share and which to password-protect is very easy, and the service automatically sets up RSS and iTunes feeds for the folders you choose to make public.The 60-day trial account includes 200 MB of storage and a 1GB transfer limit; paid plans start at $6.95 a month.

Evernote's private beta grew to include over 125,000 users (ahem), and the new public beta includes an option for a $5/month premium user plan that increases your monthly transfer quota/new note cap from 40 MB to 500 megabytes and gives you SSL for all data, priority access to the text-recognition queues and tier 1 customer support. Plus you get a snazzy t-shirt while supplies last (pink elephants on parade!). The web interface to Evernote has also gotten a facelift, with full drag-and-drop support and an improved clipper feature. Can't say yet if they've fixed the session timeout issue that ate a long note my wife was writing last night, but I surely hope so.

In a conversation a couple of weeks back, Evernote CEO Phil Libin shared some future directions for the product with us as well as a couple of tips from his personal use of Evernote.

First, what many are waiting for will be coming very soon: a native iPhone client for Evernote (shipping shortly after the App Store opens), including one-button publishing to Evernote and location tagging for every item you create from your phone, like a trail of breadcrumbs leading you back to that favorite restaurant or bargain spot. (Phil's tip: whenever he parks his car at the airport, he takes a picture of the parking spot and sends it to Evernote to help jog his jetlagged brain.)

Second, the upcoming platform-wide features for Evernote will soon include more granular controls on publishing and sharing, a revamped Windows client, Evernote for Blackberry, and audio notes. (Phil's tip: he uses Evernote notebooks to share collections of photos or screenshots, like this accidental poetry from CNN rundown.) Later this summer we should expect to see the first public release of the Evernote API, which will permit third-party devs to add features to the service (personally I'd love to have a business card postprocessor tool, which Libin sees as a good 3rd party opportunity).

Other future features are yet to be publicly disclosed, but Libin hinted that the image-processing power of Evernote's servers may be bent to teasing out specific features of photographs. Faces? Product barcodes? Geotagged landscapes? Can't wait to find out. Meanwhile, the free Mac version of Evernote (read Brett's original review here) is downloadable at evernote.com.

The cloud storage and sync offering from Sharpcast, SugarSync, has released a public beta of its OS X client today, complementing the existing Windows, web and mobile (WinMo + Blackberry, iPhone coming soon) clients. The Mac client and the Windows client appear pretty much the same, but once you set up your sync you don't have to look at the client UI very often.

SugarSync is a for-pay service that extends your local files seamlessly to your other computers, to a secure webpage, and pretty much to anywhere you think they ought to go. CEO Gibu Thomas describes SugarSync as "get my stuff everywhere," a supercharged and cross-platform version of .Mac iDisk synchronization. Our colleagues at Download Squad have checked out the service in detail, and there's a good writeup at webware.com as well.

To use SugarSync, you can define a set of folders to sync, photos to share, "Magic Briefcase" files that live in the cloud and sync down on demand, click and go -- then the defined content will be available on all your computers. With both "full sync" and "light sync" modes, you can leave rarely used files on the SugarSync side and only retrieve them as needed (great for those MacBook Air users hungry for storage). You can also selectively share photo galleries or other content via the web UI.

Once you get past the 45-day, 10 GB of storage trial period, you can use the discount available through 4/15 to get a half- off data plan (starts at $25/yr for 10 GB, up to 250 GB for $250/yr).The advantages of SugarSync for backup, specificity of synced items, and a supported client may make you give it a look as an alternative to iDisk, or to cloud solutions like OmniDrive, JungleDisk or other clients for Amazon's S3 that require you to roll your own synchronization plan.
