If you empty the Trash after deleting, it may be something else using the space.
If you're wondering what "Other" category in the Lion storage tab is about, this may help explain:

By the way, when you delete an app by dragging it to the Trash, there are frequently files and folders left behind that could consume space. The most effective method for complete app removal is manual deletion:

For space issues not explained by the above, there are a few things you can try, some of which may or may not apply:
- Begin by restarting your computer as a first step. This sometimes resolves issues.
- For Time Machine users on notebooks running Lion, space may being consumed by Time Machine local snapshots, which can be disabled.
OS X Lion: About Time Machine's "local snapshots" on portable Macs - Search with Finder to see if the space is being consumed by a very large file or several large files. Adjust the 50GB in the illustration to whatever size you deem appropriate.
- Use OmniDiskSweeper, JDisk Report, Disk Inventory X, DaisyDisk or GrandPerspective to see how space is being used on your drive. Some of these apps may show more detail than others, so try several.
- Check your drive with Disk Utility: Using Disk Utility to verify or repair disks
- Try re-indexing your drive: Spotlight: How to re-index folders or volumes
- Encrypted drive
- Time Machine backup files and needed disk repair
- App filling log file
- App or file was 89GB
- Drive needed to be re-indexed
- Time Machine backup file
- Large app cache file
- Garageband files and video podcasts
- Oversized email being duplicated
- Another email issue

Thank you GGJStudio for very helpful info. I can see why mobilebackup eat up a lot I guess 160GB SSD is not enough. 
but again many thanks.

"mobilebackup" is a backup of an iPhone or iPad or iPod touch. Try backing up to iCloud and deleting the backups from your computer in iTunes preferences. This might help a bit.
Good luck!

You are confusing two, different things.
iOS backups are stored at ~/Library/Application Support/MobileSync/Backup/
If there are backups in there for devices you no longer own they can be deleted. Do this in iTunes under preferences in the Device tab.
The data at /Mobilebackups is created by Time Machine on a portable Mac that is away from a backup source. If this space is large you can zero it out by turning Time Machine off then back on. You really don't need to bother with this though because Lion will shrink this space automatically if more room is needed on the drive for user data.
