The App Store follows trends more closely than your 13-year-old sister at Hot Topic, and often, that's a bad thing. But this week has revealed a trend I think you're going to like.

Rolando Lite: While charging full price for what should arguably be a free upgrade is one App Store trend we'd like to see die (see below), here's one that's great: lite versions of the most popular non-free games. Rolando is fantastic if you haven't played it yet, and now you can try before you buy with the free Lite, which is limited to the first stage only. Free.

Super Monkey Ball Lite: And what ho? A free lite version of Monkey Ball too with three stages from the full game? Keep it up game publishers, keep it up.

X-Plane Extreme: It's kind of annoying how X-Plane keeps packaging new planes into all-new editions of the app, charging 10 bucks for each one, but X-Plane Extreme does look pretty great. This one's bringing the military jets, from the F-22 Raptor, B-2 Stealth Bomber and the ol' SR-71 Blackbird spy plane, and they look beautiful. If you haven't bought X-Plane already and dig flight sims, Extreme looks like the version to get (there is also one for Airliners and Helicopters, if that's your thing).

Light Bike Full Version: On sale for a buck for a limited time only, this is the just-released full version of Pankaku's Tron game with the awesome two-hands-one-iPhone four-player mode we liked so much when we first saw it. Very cool. $1

Digital Bass Line: I've been wanting to play with Korg's awesome DS-10 synth software for the DS for quite some time, but until I get my hands on it, this great Roland TB-303 emulator will tide me over. The 303 is the bass synth companion to the legendary 808 drum machine, and it's reproduced quite faithfully here-really fun to play around with, even if you're not a musician. It's $5.

Almond Emulator: And finally, do you ever get the sense you're watching someone lose their mind via disconnected clues? Like, say, the iPhone apps they write? The Almond Emulator costs $1, and offers the chance to taste, smell, feel and listen to a digital on-screen almond; each button pressed simply changes the text above to read "It tastes just like an almond." Riiiiight. Probably the strangest app I've seen-kick this guy a buck, he needs it to refill his meds.
